When light enters different transmitting substances (e.g. from air to glass), about 5% of the light will be reflected away, and there are many lenses and refractors in optical scopes, which can add up to a loss of 30% to 40% of the incident light. Modern optical lenses are usually coated with single or multi-layer magnesium fluoride transmittance enhancement coatings. Single-layer transmittance enhancement coatings can reduce reflections to 1.5%, while multi-layer transmittance enhancement coatings can reduce reflections to 0.25%, so that the entire scope, if properly coated, can have a light transmission rate of up to 95%. Lenses coated with a single layer of transmittance enhancement film are usually blue-violet or red, while lenses coated with multiple layers of transmittance enhancement film are light green or dark purple.
Application of permeation enhancement membranes
Reflection-reducing film (transmittance-enhancing film) is an optical coating with a wide range of applications, widely used in daily life, industry, astronomy, ** science, electronics and other fields. With the development of the electronics industry and computers, display anti-glare anti-static film and computer video security screen has become a new field of application of the reflection-reducing film, has a broad market prospect, which can not only effectively improve the conversion efficiency of the battery, but also improve the mechanical properties of the substrate, electrical properties, optical properties, and other physical and chemical properties.
Chemical Definition of Car Coating
The definition of car coating, from a professional point of view to analyse, in order to make a difference with the glaze, the real car coating should be inorganic coating, that is, never oxidize the crystal glass coating. Only inorganic coating, is covered in the car surface coating layer, will not be ultraviolet light, acid rain and other external factors oxidation and disappear, vehicle normal use of a single protection of the paint up to 1 year or so, so it can be called car coating. Its coating method in order to adapt to the needs of the popularity of automotive beauty shops, do not need to be cured at high temperatures in the oven, as long as the chemical reaction with the moisture in the air, it can be cured to silicon dioxide (SiO2) as the main component of the crystal glass coating layer.
Chemical Vapour Deposition of Permeation Enhancement Films
Chemical Vapour Deposition (CVD) (Transmission Enhancement Film) is to supply gases containing the elements that make up the film to the substrate, and use energy sources such as heating, plasma and ultraviolet light to deposit the film on the substrate in a chemical reaction, which allows for the preparation of reflection-reducing films for solar cells, such as SiN, ZnS, SiO2, SiC, and so on.
