Although similar to a bandpass filter in theory; these particular optical filters are often achieved by depositing custom filters on both sides of a substrate using some of the newest and most progressive deposition methods to maximize the requested performance. Contact our design team to discuss your specific requirements including: transmission wavelength range, steepness of cut on and cut off transitions, optical density, angle of incidence and incident medium.
Broadband pass optical filters are available for maximum performance from 400nm – 2000nm. These filters have excellent environmental stability for demanding military and telecommunication applications.
High performance bandpass optical filter coatings are deposited on custom optics, crystals, polymers, fibers, semiconductors and glass substrates up to 200mm in diameter.
Designs meet or exceed the environmental requirements of MIL-C-48497.
