We provide a variety of cutting-edge optical thin film filters and absorptive filters.
Lyot filters and Solc filters made form Birefringent Filter Plates offer an extremely narrow bandwidth with wide angular fields or tuning capability.
Telcom filters include gain flattening filters, DWDM filters, long and short pass filters for telecommunication applications.
Laser line interference filters center on the resonance of the laser and attenuate the background optical radiation.
Single cavity (SC) filters are a special type of solid etalon in which the cavity is formed by a deposited layer of coating material on a glass substrate. It has up to 100nm tuning range and great thermal stability.
Neutral density filters uniformly attenuates optical radiation in specific spectral regions. In contrast with neutral density filters, color glass filters selectively transmit a desired wavelength range.
The infrared filters are widely used in gas monitoring, temperature sensing and thermal imaging. The infrared cut-off filters are used for CCD or CMOS imagers to produce vivid images.
