Sol-gel optical anti-reflective coating

>< /> :r= d Sol-gel optical anti-reflective coating
How much does the sol-gel optical anti-reflective coating cost? This question has caused doubts in quite a few people! With the rapid development of the mobile Internet, high-power laser anti-reflection film manufacturers are also booming, and anti-reflection film development companies are springing up like mushrooms after a rain. Their technical strength and after-sales service vary widely. Since the year, the excellent anti-reflective film technology of the Soguang Thin Film Technology Research Center has been widely welcomed by the market. As a product with stable products and excellent technology in the industry, the last special reminder is: before choosing an anti-reflective film developer However, do not cooperate with irregular developers just to get cheaper prices. This approach will only damage your own interests. Cooperating with regular developers can reduce a lot of unnecessary troubles, and at the same time ensure a long-term, good and sustainable cooperative relationship in the future. If you have any needs, please contact us. We are direct sales from the manufacturer. Contact number:, mobile phone, thank you Ms.:
The function of anti-reflection coating is to increase the light transmittance of optical surfaces. Can be used for:
, LCD panel glass
, light source backlight (D,) glass
, flat-panel light-emitting module
, ultra-thin light box, crystal light box
, various Size downlights
and various types of billboards
are materials commonly used in disposable plastic products. Polyterephthalate plastics mainly include polyethylene terephthalate and polybutylene terephthalate (B).
Generally, metals have a large extinction coefficient. When a light beam is incident from the air to the metal surface, the amplitude of the light entering the metal is rapidly attenuated, causing the light energy entering the interior of the metal to decrease accordingly, while the reflected light energy increases. Extinction The larger the coefficient, the faster the light amplitude attenuates, the less light energy enters the interior of the metal, and the higher the reflectivity. People always choose metals with larger optical coefficients and more stable optical properties as metal film materials. Commonly used in the ultraviolet region The thin metal material is aluminum. Aluminum and silver are commonly used in the visible light region. Gold, silver and copper are commonly used in the infrared region. In addition, chromium and platinum are also often used as film materials for some special films. Since aluminum, silver, copper and other materials are in the air It is easy to oxidize and reduce performance, so it must be protected with a dielectric film. Commonly used protective film materials include silicon monoxide, magnesium fluoride, silicon dioxide, aluminum oxide, etc. The advantage of metal anti-reflection film is that the preparation process is simple and the work The disadvantage of a wide wavelength range is that the light loss is large and the reflectivity cannot be very high. In order to further improve the reflectivity of the metal anti-reflection film, several dielectric layers of a certain thickness can be plated on the outside of the film to form a metal dielectric anti-reflection film. .It should be pointed out that the metal dielectric film increases the reflectivity of a certain wavelength (or a certain wave region), but destroys the neutral reflection characteristics of the metal film. The all-dielectric anti-reflection film is based on multi-beam interference. . Contrary to the anti-reflection coating, coating the optical surface with a thin film with a higher refractive index than the base material can increase the reflectivity of the optical surface. The simplest multi-layer reflection is made of two materials with high and low refractive index. It is formed by alternate evaporation, and the optical thickness of each film is one-quarter of a certain wavelength. Under this condition, the reflected light vectors on each interface that participate in the superposition vibrate in the same direction. The combined amplitude increases with the number of film layers. And increase.
