one,Polarized lensCharacteristic

The polarized lens is compressed by multi -layer thin resin materials, which is relatively lightweight.Each layer has different effects.The middle layer is a polarized layer, and its principle seems to be a shutter, which can filter out of the strange reflection light.The second and third layers can filter 99.9%of the harmful ultraviolet rays and reduce the strength of the light. The function is no different from ordinary Sunglasses.The fourth and fifth layers of polarized lenses are the anti -impact layer, making the lens not easy to break; the sixth and seventh layers are strengthened, making the lens difficult to wear.Polarized mirrors can filter out harmful light to protect the eyes.

Although polarizing lenses can filter out many irregular light interference and avoid dazzling, dazzling, etc., if the arc bend of the lens itself cannot be in the state of optical optical standard refractive state, the polarizing effect will be weakened, affecting the authenticity of the image, and durablePoor sex.

The general polarizing Sunglasses on the market are made of fibrous clip polarizing membrane.It is different from the optical glass polarized Sunglasses. Because of its soft texture and unstable arc curvature, after the lens assembly is upper frame, it is difficult for the lens to meet the optical refractive standard, and the image is loose and deformed.Due to the unstable arc curvature, the lens deforms, resulting in the clearness of the light transmittance image, the image distortion, and the effect of normal lighting.And the surface is easy to scratch, wear, and imperative.

Second, the role of polarizing mirror

The effect of polarizing mirror is to effectively eliminate and filter the scattered light in the beam.Make the light into the eye visual image in the transmittance of the light, making the field of view clear and natural.Like the principle of shutters, the light is adjusted to the same direction and enter the room, naturally makes the scenery look soft and not dazzling.Specific to daily life:

1. When driving, it will no longer bother the many reflection from the sun and the vehicles in front.

2. When fishing, the water wave shines under the sun, but you will not feel uncomfortable at all, but feel comfortable and disappear.

3. When skiing, you don't have to worry about reflective and ultraviolet rays, you can skate.

4. When it rains, the road traffic signs with rainwater flow are clearly presented in front of you.

5. During vacation, let you enjoy the sun, beach and leisure time.

Three, DaiPolarized glassesWhat are the benefits

The ideal polarized Sunglasses should have the following conditions:

1. It must be able to filter more than 99%of the ultraviolet rays in the sun, and the filtering performance meets the requirements of international standards.

2. Effectively block the function of strong light.

3. The lens has a standard optical arc design, forming an optical shaft to produce video.

4. The eye frame is firm, the frame material is excellent, and the optical function is designed. It feels comfortable and safe after wearing.

Polarized Sunglasses are a combination of substances. Generally, the two layers are combined with seven layers.In the middle, the middle layer is the polarization layer.The polarized layer is effective, but it is not wear -resistant and is easy to scratch.

The polarizer can reflect the random reflex light, glare, and irregular reflex light resistance in natural light. The inside of the polarizer has 300,000 linear lines that can not be seen in each 1 Square centimeter.direction.

Compared with ordinary glass Sunglasses, polarized Sunglasses do not affect vision and will not cause color difference.At the same time, it can effectively avoid the damage of ultraviolet rays to the eyes.

How to choose Sunglasses

1. Whether there is a polarized effect

The effect of polarizing can help us well distinguish between reflex light and objects under strong light, whether it is fishing, skiing, or driving people.Under normal circumstances, Sunglasses clamps will have this function, but the formal brand will have a polarizer test card, and it will be presented to consumers with the pattern of fish and water. Therefore, you can try it.To fish, it shows that its polarizing effect is good.

2. Whether there is ultraviolet function

When buying Sunglasses clamping, consumers must confirm whether this product has the function of anti -ultraviolet rays; if only the filtering function, it does not have ultraviolet function, it cannot be 100 % blocking ultraviolet rays.Essence

3. Check the structure of Sunglasses clamps

If it is not a formal brand, iron device is generally used, which will make the lens easily scratch and even cause damage to the eyes.On the contrary, if we choose a big brand, its quality will also be guaranteed. When the lens is in contact with it, it will avoid the separation of silicone.

How to use Sunglasses clamps

Poor Sunglasses designed for myopia people are effectively anti -glare and ultraviolet rays.It is especially suitable for outdoor sports such as driving, Outdoor, fishing, etc.Adopting polarized lens technology, the visual resolution is greatly improved.Eliminate 99%of reflection light and scattered light, making your vision more clear and Smooth.The lens is specially added to enhanced treatment, which is effective, scratch resistance, and impact.

Sunglasses clamps should be made from seven layers of special materials, each with its own functions.The polarization angle and the radian of the lens are designed according to the principles of precision optical.The wearers will never have the distortion and dizziness of the imitation products.Each lens is strengthened by the original factory, scratch resistance and difficulty in deformation, and broken.It can be used for a long time and the performance is unchanged.The production and materials of the Sunglasses clipped glasses have professional design and producers, which are comfortable and durable.

Sunglasses clamps are clamps or mirrors that are extended to design on the basis of mirror racks.It is often seen on the road that many people's glasses are also a pair of Sunglasses that can be turned down.When walking under the sun, just turn down the Sunglasses and cover the myopia lenses to play a role in Shading.When walking under the sun, the Sunglasses were fixed on the Myopia glasses rack. Others looked like wearing a pair of sun glasses; when I walked into the room, as long as the Sunglasses were taken off, it was a pair of close vision glasses.There are also three types of fixed Sunglasses, which are called "mirrors". One is to use magnets to suck directly on both sides of the mirror frame, and the other is to directly design the magnetic connection point in the bridge of the mirror frame.Another is stuck on the frame.In addition to ordinary Sunglasses, the lens also has a polarized lens.

For women who do not like Sunglasses, it is recommended that you buy Sunglasses directly, and Sunglasses also have the kind of optometry.

Let's talk about the steps of using clamps

1. First pinch the spring button of the clip to open the clip.

2. Squeeze the spring clip and clip from top to bottom in the bridge of the glasses.

3. Covered the clip to the glasses and adjust the position.

The above is the simple use step of the clamp. The clip can be selected according to the glasses style wearing.

What is polarized Sunglasses

Polarizer can be divided into three types, namely straight polarizers, ellipse polarized and round polarizers.Generally, the so -called polarizer refers to the straight line polarization, also known as flat polarization.The vibration of this light wave is fixed in a specific direction. The transmission route in the space is a sine curve, and the projection on the plane of the vertical dissemination direction is the straight line.

The plane composed of a straight polarized vibration direction and the direction of propagation is called the vibration surface. It is vertically vertically from the vibration direction and the surface of the dissemination direction is called polarizing surface.Make nature light through polarizing mirrors, and can obtain straight -line polarizers, which are often used in crystal optical research.

The classification of polarizer

1. According to the material, it can be divided into: glass mirror of glass material, resin material polarized Sunglasses, and TAC lens material polarized Sunglasses.

2. It can be divided into: Ski mirror, fishing mirror, polarized driving mirror, outdoor sports mirror, golf glasses.

How to distinguish between Sunglasses and polarized Sunglasses

The first is the relationship between the two. The Sunglasses include polarizing mirrors, and polarizing mirrors are a kind of Sunglasses.It should be said that polarizing mirrors are a special Sunglasses designed with more and more requirements and designed.

Then let's talk about the difference. As long as we do not specifically pointed out, we generally have some Sunglasses that only have the two basic functions of obstructing strong light and worry about ultraviolet rays.Such Sunglasses are relatively single, the technical content is lower, and of course the cost is lower. Now many merchants sell ordinary Sunglasses as polarizing Sunglasses, which harms many consumers.

The biggest difference between polarized Sunglasses and ordinary Sunglasses is that this Sunglasses are treated with reflected light.In the environment of our lives, there are three kinds of light: direct light, reflection light, and shot light. Among them, we can not perceive the light shot light, but it is the most important light of our eyes that can see objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see the most important light of objects; and our eyes can see objects.Direct light has a fixed light source (such as the sun), as long as it pays attention, it will not cause harm to our lives.

Only reflected light, because Smooth and flat planes can become reflexes. These common reflexes often reflect light suddenly, which will bring a lot of inconvenience to our lives.For example, driver drivers, the rearview mirror ahead is an uncertain reflective light source. The surface of the road on the road or the Smooth plane objects carried by passers -by can become a reflected light source. These reflex light may bring the driver of the driver.It is dangerous.

Polarized Sunglasses are the glare of reflected, filtering it, so that it can play a role in anti -dizziness, and traveling in summer will make the field of view more clear and reduce visual fatigue.Of course, such Sunglasses will also be much more expensive.

If you just go out, ordinary Sunglasses can fully meet your needs.But whether it is driving or outdoor activities such as mountain climbing and skiing, choosing a pair of polarized Sunglasses will make you easier and more comfortable.

When is it suitable for wearing polarizers

1. fishing

In summer, fishermen like to wear Polarized glasses.Why?The reason is very simple. Polarized Sunglasses have the effect of filter polarizing light. It is easier to wear fishing, and it is easier to watch.It feels more comfortable.

2. Driving

Polarized lenses are the most recognized lenses in the world.When the surface is reflected by the object, it is partially polarized and has a glare.The negative effect of glare -enhances brightness and weakens color saturation; the outline of the object is blurred, making glasses fatigue and discomfort.Polarized tablets make the polarization principle of light, which can effectively eliminate the special functions of glare, filter the messy light, improve the driver's vision and add fun to drive.

3. outdoor sports

Friends who love Outdoor leisure tourism are also exclusive to polarizing lenses. The polarizing mirror is composed of a balanced crystalline. This structure only allows the light waves to balance the crystal, and the light waves that shake to other angles are blocked.If the angle of the polarizer is adjusted, the shocking light reflected by the water surface, glass, flowers, water, water and other reflection can be blocked, and normal light can be partially passed, so as to enhance the contrast, reduce reflection, enhance the color of the scenery, reduce the atmosphere of the atmosphere,The role of fog phenomena makes you see the clearness of the world, and return you a colorful world, a blue sky, strong and beautiful nature.

The lens polarization angle and arc are specially designed and processed. The wearer will not have the feeling of distortion and dizziness of the scene. The resin polarizing lens has the advantages of lightness, difficulty in breaking, and easy to wear and comfortable.It is most suitable for fishing, driving, exercise, navigation, skiing, hunting, etc.

How to buy polarized Sunglasses

1. The first consideration is the quality of polarized Sunglasses

The primary function of polarizing Sunglasses is to prevent ultraviolet rays and filtrate polarized light. Good polarized Sunglasses lenses can block more than 90%of ultraviolet penetration. Please choose polarized Sunglasses with the best blocking of UV400 to the best obstruction of ultraviolet logo;The inferior polarization Sunglasses of the polarizing filtering function, such as dark Sunglasses, is darker with the light of the human eye and the pupils of human eyes will become larger, and the ultraviolet rays of the eyes will increase, increasing damage to human eyes.

2. Will there be discomfort for a long time?

Genuine polarized Sunglasses must be comfortable to wear. If you feel uncomfortable, dizzy, headache, dry eyes, tingling, etc., please take it down quickly;

Meicoscopy belongs to inferior or imitation generally causes dizziness and headaches. Generally, inferior lenses are not technical and functional when manufacturing.The damage can be described as a loss.

3. Focus on the protection function of the frame

The protection function of polarizing Sunglasses Apart from the basic functions such as anti -ultraviolet rays, avoiding strong light dazzling, and filtering glare, most polarizing Sunglasses frames are designed with surface arcs. In outdoor sports, it can effectively prevent wind and foreign body stimulation. In additionThe hardness of the lens and the flexibility of the frame of the frame must be considered whether it will hurt the human body.

4. Polarized Sunglasses should be true and natural

The color selection of polarized Sunglasses should be based on the color of the surrounding environment, the edges of the object are clear, and the principle of effectively identifying different color signal Lights.Especially when driving Sunglasses, it is guaranteed to drive safety.The color of the lens is better in gray, tea, and green, because these colors of lenses are better absorbed by infrared and ultraviolet rays, which can improve visual contrast and clarity. Wearing effects in severe air pollution or fog.

How to identify the quality of polarized Sunglasses

1. Generally, there will be instruments that detect Sunglasses to resist ultraviolet capacity. You can know if the glasses in your hands meet the standard through instrument detection.

2. The simple way to test the quality of the Sunglasses is: you can use the ultraviolet light issued by a banknote pen or a banknote check machine to observe the UV logo pattern on the RMB through Sunglasses. If the quality of the Sunglasses is poor and there is no blocking of ultraviolet rays, it can still be clearly clear.When you see the UV logo pattern on the RMB, on the contrary, if the quality is excellent, you can't see it.

Polarized Microscope principle

1. Single refraction and dual refractive

When the light passes through a certain substance, such as the nature of light and the pathway does not change due to the direction of illumination. This substance has "different sexual sex" in optics, also known as single refractive body, such as ordinary gases, liquids, and non -crystalline.Solid; if the light is through another material, the speed, refractive index, absorption and polarization, amplitude of the light are different due to the illumination direction.Such as crystal, fiber, etc.

2. The polarization phenomenon of light

Based on the characteristics of vibration, light waves can be divided into natural light and polarizing light.The vibration of natural light is characterized by many vibration surfaces on the vertical light wave conduction shaft, and the amplitude of vibration on each plane is the same; natural light is reflected, refracted, double refraction and absorption, etc.Given light waves are called "polarizing" or "polarized light".

3. The generation of polarization and its role

The most important part of polarizing Microscope is polarizing device -polarizer and polarizer.In the past, both of which were composed of Nicola prisms. It was made from natural squarestones, but due to the large limitation of the crystal volume, it is difficult to obtain a large area of polarization. Polarized Microscope uses a artificial polarizer to useReplace the Nicor Slutter.The artificial polarizing mirror is made of sulfate, also known as the crystal of HERAPathite, which is green olive.When ordinary light passes through it, it can obtain a straight line polarizing light that is only vibrated on the line.

Polarized Microscope has two polarized mirrors, one is called "up mirror" between the light source and the object of the object;Attachment is for operation, which has the scales on the rotation angle.When the light from the light source through two polarized mirrors, if the vibration direction of the mirror is parallel to each other, that is, when the "parallel inspection bias" is in the case, the field is the brightest.Conversely, if the two are vertically each other, that is, when they are in the "bias of the Zhengjiao school", the field of view is completely dark. If the two are tilted, the field shows a medium degree of brightness.It can be seen that the straight line polarization formed by the mirror, if its vibration direction is parallel to the vibration direction of the mirror, it can be completely passed; if the partial slopes are oblique, only a part is passed; if it is vertical, it cannot pass.Therefore, when a polarized Microscope is used, in principle, the upper -mirror and mirror mirror should be carried out in a state of positive cross -check bias.

4. Double refractive body under the bias of the right inspection

In the case of orthogonal intercourse, the field of view is dark.The vibration direction of the polarized light formed does not change, and the vibration direction of the vibration of the mirror is still perpendicular to each other.If the inspection object has dual refraction or substances containing dual refraction characteristics, the vision field with dual refraction characteristics is brighter. This is because the straight -line polarization light shot from the upper mirror enters the double -folding body, and the vibration direction will generate the vibration direction.Different two kinds of linear polarization light. When these two Lights pass the mirror mirror, because another beam of light does not orthogonal with the direction of polarizing mirror polarization, you can see the bright mirror.elephant.When the light is dual -refractive, the two polarized light vibration directions are formed, which are different according to the type of object.

When the dual refractive body is orthogonal, when the rotating loading table, the elephant of the dual folding body changes four times in the rotation of 360 , which is darkened every 90 every 90 .The position of the darkening is the two vibration directions of the dual refractive body consistent with the vibration direction of the two polarizers. It is called the "light position" rotating 45 from the lighting position and the body becomes the brightest. This is "The diagonal position ", because when deviating 45 , when the polarizing light reaches the object, the light can be decomposed by the mirror that can be detected by the mirror, so it is bright.According to the above basic principles, the use of polarized micro -surgery may determine the same oriental (single refractive body) and the opposite sex (dual refractive) substances.

5. Interference color

In the case of biased positions, the dual refractive body is observed as a light source with a variety of different wavelengths. When rotating the carrier table, not only the brightest diagonal position appears in the field of view, but also the color.The cause of color is mainly caused by interference colors (of course, the object itself may not be colorless and transparent).The distribution characteristics of the interference color determine the type and its thickness of the dual folding body. It is due to the dependence of the wavelength of different colors of light.The color of the mirror light is different.

Polarized Microscope use precautions

1. The laboratory should have three anti -prevention conditions: shockproof (far away from the source of the Earthquake), moisture -proof (using air conditioners, dryers), and dust (floor floor).Power: 220V -10%, 50Hz temperature: 0 degrees -40 degrees.

2. Be careful not to make the material mirror encounter the sample to avoid scratching the material mirror.

3. Do not switch the mirror when the center of the loading table is close to the center of the object mirror, so as not to scratch the material mirror.

4. Brightness adjustment should not be large and small, and do not light up, affect the service life of the Light bulb, and at the same time damage.

5. Switch all the functions, the movement should be light, and in place.

6. To minimize the brightness when shutting down.

7. Non -professional personnel should not adjust the lighting system (filament position light) to avoid affecting the quality of imaging.

8. Pay attention to high temperature when replacing the halogen Lights to avoid burns; be careful not to directly contact the vitreous of the halogen light with your hands.

9. When the shutdown is not used, adjust the material mirror to the minimum state through the focusing mechanism.

10. Don't use it if you don't use it, don't immediately cover the dust cover, and then cover it after cooling. Pay attention to the fire prevention.

11. The optical components that are not used often are placed in a dry dish.

12. Non -professional personnel should not try to wipe polarized Microscope mirrors and other optical components.The eyepiece can be dipped in a 1: 1 ratio (aquatic alcohol: ether) mixed liquid to dry after dried the sector cotton swab. Do not use other liquids to avoid damaging the mirror.

The difference between polarizing Microscope and ordinary Microscope

The main difference between polarizing Microscope and ordinary Microscope is equipped with two light components on the polarized Microscope, that is, polarizing mirrors and detect polarizers, so the structure of polarizing Microscope is more complicated than biological microscopes.Polarized Microscope is the purpose of analyzing and testing of crystal optical characteristics through the role of these two polarizers.

When testing the crystal, the polarized Microscope is placed on the carrier between the Polarized mirror and the Polarized mirror.The vibration surface of the two polarized mirrors should be vertical (orthogonal), then the field of view is the special nature of dark use of light polarization. It is applied to microscopic imagery technology and promotes the rapid development of crystal optics.The principles and methods of crystal optics are used to study minerals, rocks, slag, and refractory materials, which are convenient and accurate, so they are widely used in geological research and gold phase research.There are basically two ways to observe with polarized Microscope:

1. Use small pores to light up the light beam to light up the object. At this time, you can think that all the beams are perpendicular to the plane of the object, and you can directly observe the image of the object with a eyepiece.

2. Using a large -pores to concentrate on the light beam to illuminate the object. At this time, the pupils of the objective mirror will produce interference phenomenon that indicates the nature of the objects observed.Interfering images formed.

[Driving glasses] What are the effects and principles of driving lens?

The role and principle of driving mirror

Driving lens (also known as driving glasses, driver glasses) is a kind of Sunglasses, a kind of glasses used by polarizing Sunglasses and suitable for driving (driver).

The role of driving mirror

During the driving process, there are various reflex light and glares from different objects (such as glare and glare of the car) from different objects. The polarizer can filter out unnecessary light, make the sight more clear, drive safer, and 100 can be 100.%Block harmful light.Gray or dark green lenses can maintain the most natural original colors when visually, which is a good choice.

Driving mirror material

Levels: Polarized lenses meet relevant standards. If UV prevention should be above 99%, it is not easy to break.

Frames: aluminum -magnesium alloy, pure titanium, etc.

Principles of driving mirror

Driving glasses are designed according to the principle of precision optical principles based on the angle of the lens polarization and arc, which only allows light to pass the light of the polarization direction, while other strong light sources (such as the sun, water, glass, and aspirational road)Foreign light interference, avoid flowers, dazzling, dazzling and other phenomena, making the sight clearer and softer.

Replenish:

Commonly used methods to distinguish glasses: you can put Sunglasses in front of your eyes, observe the distant targets through lenses, such as window frames or door frames, and then move the glasses up, down and back, the target should not be swinged and wavy deformation.

Why wear a driving mirror: Natural light (non -polarized aurora) is actually composed of electromagnetic waves that will vibrate in a specific direction, and light that is reflected or scattered usually prefers a specific direction.Because the roof or pool reflects the sunlight; after the natural light is filtered by the polarized lens, it can only be passed by the light in the direction. That is to say, the polarized lens can first be polarized by the light, and only the light in one direction passes through the direction.(Viewed) Polarized driving mirror is to use this feature to block harmful light, because the sunlight will cause harmful glare if it is touched by any object, and the polarized driving mirror can completely absorb these will cause dazzling and dazzling and dazzling andThe strong light of the eyes is damaged, and the driver of the driver's vehicle often encounters the strong light of the car lights coming on the face, causing the vision to be unclear. If wearing a driver's mirror, it can eliminate unclear vision caused by strong light.

Misunderstanding: Driving the mirror at Night

The so -called night driving mirror is just a colored polarized lens with light increase.Since it is a non -ferrous lens, the light will weaken.Due to the dark light at night, when wearing a colorful lens, it will reduce the visual clarity and affect the judgment.Of course, when you meet the car, wearing a driving mirror can eliminate the vision caused by the strong light of the opposite side light. However, from a medical perspective, it is not recommended to wear it for a long time, or you can wear it in the urban area. Try not to wear it as much as possible.Driving the mirror at night can not only be worn at night (in the evening). It can be worn when the light and other Lights such as rainy days, fog and sky are relatively dim. It can effectively eliminate the vehicle headlights to produce glare, increase color saturation, and have the function of lighting, so that driving is madeThose who have a clear field of vision and more accurately understand the road conditions.

What are the misunderstandings of driving glasses?

Misunderstanding 1: The darker the color, the better

Many people take it for granted that the deeper the color, the better the ultraviolet function.In fact, the function of Sunglasses filtering ultraviolet rays is only related to the plated membrane, and the color is not deeper, the better.Especially for the long -distance driver, if the Sunglasses we wear are too darker, the eyes are more prone to fatigue, and it is more dangerous to enter the tunnel and other Lights from strong sunlight.

Misunderstanding 2: Polarized lens is the most suitable

Many drivers like to wear polarizers. Indeed, polarizing mirrors can weaken strong light, eliminate glare, and make the sight naturally soft, but in fact, polarizer is more suitable for large -scale reflective environments such as fishing and skiing.The scene with darker light, polarizing mirror is easy to make people suddenly dark.In addition, polarizing mirrors can make LCD screens,ledThe color of the red and green Lights fade.Therefore, when choosing a Polarized mirror, it is best to choose a good quality optical lens. When crossing the tunnel, it is best to remove the glasses in advance and blink more.

Misunderstanding 3: Do not wear myopia mirrors

Some drivers are slightly myopia, and they usually don't wear myopia mirrors when they are driving.But once you put on Sunglasses, the problem comes: the eyes are more prone to fatigue, the vision will decrease, just as it will be affected by driving vision at night.Therefore, the driver of slight myopia usually has no problem with driving. If you want to wear Sunglasses, you must be equipped with a lens with myopia.

Misunderstanding 4: Sunglasses color is too fancy

Fashionable young people will have a variety of colors of Sunglasses. It is not false, but it is not suitable for use when driving. For example, pink and purple lenses will change color and spectrum.In fact, Sunglasses are best used in gray lenses because the basic chromatography will not be changed.Followed by dark green.Camellia and yellow lenses have the effect of improving brightness, which is more suitable for foggy, dust and other environments.
