Product description
Zhongce Optoelectronics owns multiple vacuum coating machines and a Lambda900 spectrophotometer. It undertakes the coating services for fiber optic connectors, patch cords, G-lenses, C-lenses, glasses, and crystals from external customers.
The anti-reflection (AR) coating is a kind of hard and heat-resistant oxide film. When it adheres to the surface of an optical device, it can minimize the reflection on the device surface within a specific wavelength range. The transmission characteristics of the coating depend on the wavelength of the light in use, the refractive index of the substrate, the refractive index of the coating, the thickness of the coating, and the angle of the incident light.
