What color is good for Telescope lens coating?

Careful friends may find a light color on the lens of your Telescope, especially from a angle. It is even more obvious.Some are blue and some are green.Do you think of this layer of color?The color of the Telescope lens refers to a layer of color with the surface of the eye mirror and object mirror as the surface of the car film. We are also called the lens film.

1. The role of the optical lens film: The physical principle is to destroy the scene observed from the lens under the light of direct light, which causes unreal imaging. In order to enhance the authenticity of the vision, it will be plated on the surface of the eyepiece and the surface of the objective mirror.Movies to increase light transmission, reducing the reflection of eye lens to light is that the observer can receive more light for easy observation.

2. The color classification of the glasses film: there are two types: single -layer membrane and multi -layer membrane.Single -layer membrane can only be used in a relatively simple entry -level Telescope, which can only be used in the light.Multi -layer membrane can increase the light of many bands, which can well eliminate the magnifying bias of the magnifying scene and improve the brightness of observation.Green film is a common multi -layer film, and the more formal green film Telescope in the market.Of course, the red -called infrared membrane is also a multi -layer membrane but most of the market is fakes.

3. What kind of film is good for the Telescope?It is a blue film or a good green film. This is the problem we care about.From the above -mentioned introduction, it can be seen that the green film lens is better than the red film. The red film as a monochrome will look monotonous and boring. After observation, it is easy to feel discomfort and cause eye fatigue.Green film is technically more difficult than the red film. The green membrane will be more comfortable and relaxed, and the transparent band is wider and more broad.

4. Personally think that novice friends can choose cheap blue film Telescope when they buy, because entry -level friends only understand the knowledge and skills of the use of Telescope through it.The quality of the mirror is not so high, and it is more affordable. Try the hand first, and it will be different when you get the good quality.Friends who have higher requirements for Telescope can choose green membrane lenses or even more advanced lenses.

What is polarized clamp

Everyone may encounter the sunlight when driving, and the eyes are too strong. As we all know, it is well known that if the driver's sight is poor, it is very likely to cause a traffic accident.At this time, you need a good Sunglasses. However, many myopia friends say that wearing Sunglasses is a very difficult thing for yourself. Ordinary Sunglasses are very difficult to load your eyes. myopia Sunglasses vision of the vision of myopia Sunglasses.The correction effect is not satisfactory, so what does this do?I recommend a very convenient product here -Sunglasses.

What is Sunglasses clip

Everyone knows the Sunglasses, but what is the Sunglasses clamp? In fact, it is very simple. The Sunglasses clamping the mirror legs on the basis of Sunglasses, and a clip is added between the two lenses.In this case, myopia friends can use Sunglasses very conveniently, so they don't have to worry about wearing two glasses.

Types of Sunglasses polarizers

The first is color lenses. The most common is pink lenses. It is average in sunlight and ultraviolet filtration. The main advantage is that the price is cheap.Then there are tea colors and gray types. This kind of optical fiber filtration ability is strong, but the price is also more expensive.

Secondly, there are coating lenses. This kind of lens uses coating on the mirror to reflect light to protect the eyes. In addition, this Sunglasses will reflect the rainbow -colored light when wearing, and it looks cool.

There is also a relatively special Sunglasses, yellow Sunglasses, which is generally common in shooting competitions. If you want to observe more clearly, users can consider this yellow Sunglasses.

Six major lenses classification

1. Anti -light protection lens

This lens is coated with a thin layer of magnesium fluoride on the surface to prevent strong light reflection, making you see things clearer and not disturbed by strong light.To detect whether your Sunglasses really use anti -light protective lenses, you can align the light sources. If you see purple or green reflex, it means that the lens does have anti -reflected protective membranes.

2. color lens

Also known asThe "staining lens" is to add some chemicals during the lens production process to make the lens appear color to absorb the light of a specific wavelength.This is the most commonly used lens type used in Sunglasses.

3. color -painted lens

The effect of this lens presented is the same as that of color lenses. It is only made of different ways. It is to apply color to the surface of the lens. The most well -known is"Gradual -like coloring lenses", the color is the deepest, and then it is lighter.Generally, Sunglasses with a degree of degree are mostly treated with color -coating.

4. Polarized lens

In order to filter the dazzling light in the water surface, land or snow, add vertical special coatings to the lens, which is called polarized lens.It is most suitable for outdoor sports (such as: maritime activities, skiing or fishing).

5. Trimming lenses

Some people call it"Optical lens".Because the chemicals of silver are added to the lens, so that the original transparent and colorless lenses will become colored lenses when encountering strong light, so it is suitable for indoor and Outdoor simultaneous use.

6. Meicoscopy

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.eliminate99%The reflection light and scattered light make your vision clearer and soft.The lens is specially added to enhanced treatment, which is effective, scratch resistance, and impact.

precautions for Polarization of Polaries

Because most of the purchasing Sunglasses clamps are myopia users, it is recommended that you choose yellow Sunglasses as much as possible when buying. This Sunglasses have a small degree of distortion of things. Otherwise, after the distortion of two pairs of glassesThe distance and shape.

1As well asUV prevention function

When we buy an external Sunglasses, we must first confirm whether the purchased product has the function of anti -ultraviolet rays. If there is no ultraviolet function, it is not possible to block the damage to the eyes by ultraviolet rays.Before buying, general merchants will have a banknote test machine or a professional instrument to prevent ultraviolet rays. Testing with instruments is simple and fast.Use the banknote check machine to identify, you can100Yuan's banknotes are placed in the banknote inspection machine, and then the lens is used to block ultraviolet rays to see if there are still anti -counterfeit marks. If the anti -counterfeit mark appears, it is not anti -ultraviolet.

2As well asWhether the external clamp has a polarized effect

The polarizing effect helps us better distinguish the objects under strong light and reflect light, and can improve our visual effects regardless of driving, skiing, or fishing.General external Sunglasses will have this function, but in order to buy a rest assured product, we can use the mall's polarizing test card for testing. GenerallyEffect lens.If there is no polarizing test card, you can also cross the two polarized lenses to overlap and overlap. You cannot see the polarizer of the lens outside the object, and the non -polarized product can be seen.

3As well asOverall structure of external clamps

Many of the tight device on the polarized clamping sheet are iron, which is easy to scratch the lens.When we choose the product, pay attention to the smoothness of the product to avoid scratching our glasses.The force point of contact with the lens requires special attention. Pay attention to whether the contact point of the product is fitted with the lens and whether there is rubber/ /Silicone is separated.Do not choose an external clamping piece of metal products, which can easily cause the lens to scratch and affect vision.

In fact, most Sunglasses manufacturers have made Sunglasses. When choosing, everyone pays attention to choosing the famous Sunglasses brand, such as Tyrannosaurus, Ray Peng, Versace, Buick, Bao Sheng, etc., are all good choices.For more well -known brands of polarizers, please refer totop Ten brand brand Rankings of PolariesEssence

Xiaobian concluded: Although Sunglasses can effectively protect the eyes and play a purpose of playing handsome, it is not suitable for wearing Sunglasses at all times, such as the interesting report, banquet, and wearing Sunglasses at night.Excience, so wearing Sunglasses must also pay attention to time, occasion, working environment, etc.Okay, the introduction of Sunglasses clamps is here. Let's buy Sunglasses folder that suits them.

Astronomical Telescope eye mirror type Introduction of astronomical Telescope mirror structure diagram

1. Huachangs mirror (H)

The Dutch scientist Huachaus was designed in 1703. It is composed of two flat convex lenses. The front is a field mirror and the back is a mirror. Their convex surface is facing the end of the object mirror. The focal length of the field mirror is generally 2-3 times the mirror.It is half of their focal length.Huachangs mirror is about 25-40 degrees.In the past, the Huachangs mirror was the first choice of a small refraction mirror, but with the increase of the light power of the Telescope, the disadvantages of the obvious disadvantages of the field of view, low contrast, color difference, and ball differences. Therefore, this structure is generally generally generallyUse the eyepiece of the Microscope.

2. Romans Deng mirror (R)

The design was successful in 1783, and it was also two -sets and two groups of structures. It was composed of two flat convex lenses with the same focal length and the same focal length.The spacing is 2/3-3/4, which is the focal length of the two. The color difference is slightly large, and the field song is significantly reduced. The field of view is about 30-45 degrees. At present, it is rarely used.

3. Klena mirror (K, RKE)

It was developed on the basis of Ranzesden mirror. It appeared in 1849. The main improvement was to change the single -piece lighting mirror to the dual -glued color differential lens, which greatly improved the improvement of color difference and edge image.At 40-50 degrees, there is a comfortable pupil distance when it is low, so it is currently widely used in some low-dimensional Telescopes, but it is not well performed when it is high.In addition, the field mirror of the Kelna eye mirror is close to the focal plane, so that the dust on the field mirror is easy to images and affects observation, so pay special attention to cleaning.

A US company has further improved on the basis of Kylene mirror and developed RKE eyepiece. The edge image is better than the classic structure.

4. Abbey disorders (or) (or)

Designed by Abe, one of the founders of Germany's Zeiss Company in 1880, it is a structure of four pieces and two sets. Among them, the field mirror is a three -glue lens, and the mirror is a flat -convex lens.Like and the field of the field to the degree of difficulty, it also has a flat field of viewing and sufficient pupils at a flat field of 40-50 degrees. It has a good performance in each magnification and has been widely adopted.

5. Ailifer wide -angle mirror (ER)

The successful development in 1917 was designed for military Telescopes that needed a large field of view. It was the originator of all wide-angle mirrors. The structure was 5 pieces and three groups, and the field of view was as high as 60-75 degrees.It is very suitable for observing deep space celestial bodies. Because the edges are scattered, it is not suitable for high -power design. Its performance in low times is very good.

6. Prove mirror (PL)

Also known as symmetrical mirror.It is composed of the two sets of two sets of dual -gluing color differential lenses. Its parameter performance is equivalent to OL eyepiece, but it has a greater pupil distance and field of view. The cost is lower, and it is suitable for all the magnitudeThe eyepiece has been assigned a variety of improved types.

7. Nagler's eyepiece mirror

A high -end eyepiece designed by Americans in 1979 has an amazing field of 82 degrees, high -quality edges like quality and comfortable pupils, as well as complex structures and high prices, and weight of more than one kilogram.

What is polarizing mirror

Polarized glasses have a glare of reflection and filtering them, such as strong light in summer, which can prevent dizziness.Let the field of vision have clear and natural glasses and reduce visual fatigue.Polarized lenses can completely block the dazzling glare caused by various factors such as scattering, folding, and reflection.At the same time, ultraviolet light that is harmful to human eyes can be completely blocked.

If you need to concentrate your spirit for a long time, such as fishing, driving, etc., you can choose Polarized glasses, because polarizing Sunglasses have the effect of filter polarization, which can exclude external uncomfortable light and make the scenes look soft and not dazzling.Can truly achieve the function of protecting the eyes.

What is Sunglasses

Sunglasses, also known as Shading mirror, for Shading.In the sun, people usually rely on adjusting the size of the pupils to adjust the light flux. When the light intensity exceeds the human eye adjustment capacity, it will cause damage to the human eye.

Therefore, in the venue of outdoor activities, especially in summer, the sunshade needs to be used to block the sun to reduce the damage caused by the fatigue or strong light stimulation caused by the regulation of the eyes.

The difference between polarization and Sunglasses

1. Sun mirror

Generally, the functionality of the Sunglasses is relatively single, which only has two basic functions of blocking strong light and filtering ultraviolet rays.Compared to polarizing mirrors, the technical content of Sunglasses is relatively low, and the cost is relatively low. Consumers can watch the occasion to choose. If it is used for daily decoration, or just go out for a short time, ordinary Sunglasses can fully satisfy you.Need.

2. Polarized mirror

Polarized glasses have polarized properties. The production process is mainly aimed at glares in life, and they are relatively targeted, so the price will be slightly higher than ordinary Sunglasses.Polarized mirrors can block uncomfortable strong light, and at the same time protect the eyes from ultraviolet damage. Generally, Sunglasses only use the effect of reducing light, because general lenses cannot filter the light, so it can only reduce glare, ultraviolet light, etc.The intensity cannot completely block these harmful light, so its function is to reduce the damage of the eyes.In addition to blocking the strong light, the Polarized mirror also effectively filters and removes glare, which is like the principle of shutters, which makes the light adjustment into the same direction and enter the room, naturally make the scenery look soft and not dazzling.It is the polarization of the light, which can be blocked by the harmful light without affecting the visual light, which can truly achieve the function of protecting the eyes.
