Do you know how to test customized CB Layer Coating lens? Let’s take a look at it with the editor below!
1. The relationship between anti-reflection film and anti-wear film
The anti-reflection coating on the surface of the lens is a very thin inorganic metal oxide material (thickness less than 1 micron), hard and brittle. When it is plated on a glass lens, since the base is relatively hard and the grit is scratched on it, the film is relatively difficult to be scratched; but when the anti-reflection film is plated on the organic lens, because the base is soft, the grit is Scratched on the layer, the film is easily scratched.
2. Frosted test
Place the lens in a promotional material containing gravel (the grain size and hardness of the gravel are specified), and rub back and forth under certain control. After the end, use a haze meter to test the amount of diffuse reflection of light before and after the lens is rubbed, and compare it with the standard lens.
3. Steel wool test
Use a specified steel wool to rub the surface of the lens for a number of times under a certain pressure and speed, and then use a haze meter to test the amount of diffuse reflection of the lens before and after the friction, and compare it with the standard lens. Of course, we can also do it manually, rub the two lenses the same number of times with the same pressure, and then observe and compare them with the naked eye.
In summary, the editor tells: About the introduction of customized CB Layer Coating lens testing knowledge, you can learn more about it through the above introduction.
