- Filter coating is a type of optical coating that is used to modify the transmission, reflection, or absorption of light in a material. The coating works by selectively reflecting or transmitting certain wavelengths of light while absorbing or reflecting others.
- The benefits of filter coating are numerous. By modifying the transmission or reflection of light, the coating can improve the functionality and performance of the material. For example, a filter coated with an anti-reflection coating can reduce unwanted reflections, while a filter coated with a bandpass filter coating can isolate specific wavelengths of light.
