Vacuum coating equipment glass lens coating knowledge

Basic knowledge of vacuum coating equipment glass lens coating, you know, there are no objects on the light reflection, this is the reason that we can see things. For the lens, in order to be able to make the light through the lens completely, in the film fully reflect the true nature of the situation, the best shot is through a variety of light completely. High-quality optical glass, which can reach 90% light transmittance

Above, the remaining light loss on the need of the lens surface coated film to compensate. Therefore, in the optical lens mainly antireflection coating plated also called AR coating. In order to meet various requirements, often require coated multilayer film. In order to improve scratch resistance of glass, the outermost layer tend to be high-hardness film. In the laboratory, modern technology can reach almost one hundred percent of light through. This is so because in actual use will be more or less affected by dust, dirt, etc. on the lens, making the reduction of light through the lens. Film in many ways, but also so several conventional methods.
