Optical filters are playing more and more important role in light industry and they are widely used in analytical and clinical instruments in life sciences, biotechnology, drug discovery, and industrial markets etc. CTS supply colored glass material by China to Schott, Hoya, and other manufacturers. They include short pass, long pass, band pass, ultraviolet, infrared, heat absorbing, and color temperature conversion filters. Just point and click on the name above to view information on that manufacturers filters. Absorption, and particularly wavelength selective absorption is an important factor in the　function of the filters. The two most common absorbers are thin metallic films which are particularly insensitive to wavelength for absorption, and colored glasses which absorb wavelengths varied by as much as several orders of magnitudes in only tens of nanometers. Interference filters are multilayer dielectric thin film devices.
