RICH Optical Filters｜Professional Optical Filters

RICH optical filters use high-quality borosilicate glass combined with ion-assisted deposition technology to provide precise and stable spectral control.
Suitable for image sensors, lighting systems, and optical modules, our filters include anti-reflective (AR), infrared cut (IR-cut), ultraviolet pass (UV-pass), and color filters.
They enhance optical efficiency, improve color performance, and reduce system noise.
Custom spectral specifications, shapes, and sizes are available, ideal for precision instruments, automotive modules, and wearable devices.
