Giai optical window
Giai optical window is the result of grinding and polishing after forming two mutually parallel surfaces of the optical glass. They are used to protect the original when used between two environments, but they have little effect on the visible light passed. The commonly used coating has antireflection film (AR) and scratch resistant membrane (AS), and it can also improve better effect according to customer needs, and it can be waterproof, dust-proof and scratch resistant, and customized according to customer requirements.
The anti reflection (AR) filter function is used to reduce the reflection of light and increase the penetration strength. As long as we want to enhance the intensity of light penetration, there is the existence of it. Because all kinds of sheets are widely used for surface protection of screen before display system, there is about 10% reflectivity on the surface, forming environmental reflection phenomenon, which makes the display level of the whole system drop. The company provides various specifications of the anti light plastic sheet, the reflectivity from the original 10% to 1%, is the screen to protect the screen, the ideal choice of optical window. The AR film is sometimes used in optical windows with a dust proof film or a hydrophobic membrane.
The waterproof and dust-proof membrane reduces the contact area between water and dust and the lens to a 110 degree angle, so that it can not adhere to the surface of the lens. Therefore, the surface of the filter will be more polished, which will increase the function of waterproofing, anti fogging, dustproof and fingerprint prevention. It can be widely used in camera lens, window film of electronic digital products, touch screen and other optical products, such as dust proof film. Usually, waterproof and dust-proof film is used together with antireflection film on window products. It can also increase the hardness of lens surface and prevent scratching. The scratch prevention is not 100% of the scratch injury, here is the conventional small scraping, the window to play a protective role. This coating can also be used with the reflective film in the car rearview mirror product. When the water in the filter on the surface like falling to the lotus leaf can be quickly slipped to keep a clear view of optical window.
