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.

1. What is the relationship between the tone and hardness of the fishing rod

The common hardness (H) of Fishing rods is marked with about 3H, 3.5H, 4H, 5H, and 6H, but there are also 10h and above. The higher the value of this H, it means that the harder the fishing rod is.So what is the tone of the fishing rod?It is very simple. After bending the fishing rod, look at the length of the previous part, and the ratio of the length of the non -curved part of the rear part can be divided into 37, 28, 19, etc.So what is the relationship between H value hardness and tone?Look down.

The tone and hardness of the fishing rod are not too much. They are two completely independent data.For example, a 6H fishing rod can be tuned 19, 28, or even 46.If you have to give a relationship, the higher the hardness of the hardness will be slightly smaller, maybe 19, 28, and 46, 55 less.That is to say, if anyone says that the higher the H on the fishing rod, the higher or lower, this is pure flicker, and fishermen cannot be fooled.

How to distinguish the tone and hardness of the fishing rod

1. Definition differences:The tone of the fishing rod refers to the stress bending point of the fishing rod. The simplest method is that the horizontal holding rod is bent as the bending position when the rod is beaten as a judgment basis.If bending from 2: 8 indicates that the fishing rod is 28 tuning, if the fishing rod bending from 3: 7 indicates that the fishing rod is 37;The hardness refers to the overall bending ability of the fishing rod. Generally, the first letter H of the digital plus English word Hardness Hardness H, but the hardness of the fishing rod does not have a uniform standard or each fishing rod producer has its own standards, soThe hardness of the same H value produced by different manufacturers may be different.

2. Classification differences:The tone can be divided into 19 tuning, 28 tuning, 37 tone, 46 tone, etc., the smaller the number, the harder.The hardness can be divided into 3H, 4H, 5H, etc., the larger the number, the harder.

3. Different from the judgment method:When judging the tuning, you can hold the horizontally of the fishing rod and shake, and determine it according to the position of the force point.Judging hardness can refer to the marking of the pole body.

[car navigation instrument] What are the factors of the vehicle navigator function?

The car navigator can be said to be portable navigation of large screen.The high -definition screen allows the owner to enjoy the visual impact during his free time, and the upgraded sound quality effect makes the owner fascinated.If you have a car, the preferred entertainment facility on the car is the car navigator.With the rapid development of my country's automobile industry, the sales of automobiles have been increasing, which brings a great development opportunity for the automotive electronics industry.The car navigator combining navigation and entertainment functions has become the first choice for many car owners.

The market conditions of the car navigation instrument are hot, and many businesses have also watched the business opportunities, and the car navigator of various brands came into being.Among the many products, I have summarized a few personal experience here for everyone.

car navigator function

navigation is the cornerstone of the vehicle navigator function. All other functions can be said to be attached to navigation.So how can we distinguish the quality of navigation functions?

First, check the map used in navigation, and the accuracy of the map determines the accuracy of the navigation function.

Second, the reaction speed of the GPS satellite. During the navigation process, the number of satellites displayed by the vehicle navigator is the display of the signal. The speed of the GPS reaction determines the time required for the owner to plan the route and adjust the route in the navigation.

Third, when the owner uses the navigation process, at each forkkin, each turning point, the accuracy and early performance of the voice broadcast will help the owner in a timely manner.Fourth, in the process of navigation, some intersections will show real maps. See whether real maps are consistent with real road conditions.

car navigation instrument music sound quality

As a person with a car family, there is no music on the car like a glass of boiled water, which is calm and tasteless.Traditional broadcasts and slightly rough music make car owners very useful. Now, traditional equipment can no longer satisfy people's love for music on the car, coupled with the full -scale audio speaker settings of car student manufacturers, people are pursuing high high.Quality music has been raised to a new height again.Therefore, in the car navigator, various styles of music settings are endless, powerful bass effects, and shocking penetration. This sound setting makes your journey full of energy.

Other functions of the car navigator

The function of the car navigator is still many.For example, Bluetooth, car digital TV, video player, USB interface, etc. In general, these functions are similar in products on the market, which may be that the resolution of the video player is somewhat different, but as a car owner, the eyes are the eyes are the eyes are the eyes are the eyes are the eyes are the eyes are the eyes are the eyes are the eyes are the eyes.The most important thing is that in the process of driving, Ken Ben would not have a hard time watching the video.

Edit Conclusion: The current stage of the car navigator is navigation plus entertainment function. The navigation function is constantly improving, and the accuracy can always have misunderstandings. That is because the country's road construction is too fast.The entertainment function is gradually improving.In the future, the car navigator will definitely develop another function, that is, the integration of other product functions. Personally, it is believed that that may be the function of the radar speed meter, and its powerful entertainment function will also see the computer in the future.
