Optical Coating
Super-black
It is a coating technology that implements black by absorbing light from ultraviolet, visible, and infrared bands to maximize the absorption rate of visible light wavelengths (400nm to 700nm).
Principle
It is a vacuum thin film deposition technology that uses a vacuum thin film deposition machine to coat the thickness of high-refractive chemicals, low-refractive chemicals, and absorbers differently to reduce visible light penetration and increase absorption through interference phase distance.
Effect
- Improve the design of the product’s appearance with a deeper black than the existing black.
- Advanced Camera Module Appearance
- Avoid scattering of light
