The colored glass bandpass optical filters transmit in the ultraviolet (UV) wavelength region and absorb in the visible wavelength region. They are offered in 12.7 and 25.4 mm diameter or 50.8 mm square sizes and are coated for better resistance to humid environments.

Select color filters are made from hygroscopic material which, when exposed to a humid environment, will start to discolor. Our new colored glass filters are coated with SiO2 film that protects the hygroscopic material from humidity and prevents staining. Humidity tests were conducted per MIL-C-48497 specifications. The film layer proved intact and optical performance of the filter remained the same after the test. In addition, the coated filters have a lower per surface reflectivity resulting in ~3% increase in transmission compared to the uncoated filters.
We offer a wide variety of optical filter mounts for securing and locating your optical filter. Popular types include:
