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.
