Abrisa Technologies Datasheets for Optical Bandpass Filters

Optical bandpass filters are designed to transmit a specific waveband. They are composed of many thin layers of dielectric materials, which have differing refractive indices to produce constructive and destructive interference in the transmitted light.

Product Name Notes
Notch (Minus) Filter Notch filters block a relatively narrow band of wavelengths between shorter and longer pass bands. This example narrow band minus filter has a nominal bandwidth of 110nm with an average...
Band Pass Filters These filter coatings transmit varying wavelength bands, which are determined by two cutoff wavelengths. Filters can be made at any given wavelength from near ultraviolet to near infrared.
Infrared (IR) Covert Filters This covert filter design blocks energy with wavelengths shorter than 825nm. Typically used with infra-red cameras, scopes, and night vision goggles for surveillance, these filters enable infrared energy to be...
Dual Notch Filter This dual notch color corrector improves Color Rendering Index (CRI) for output from a metal halide arc lamp. Requests to provide custom color correction for your specific lamp spectrum are...
Infrared (IR) Semi-Covert Filters This semi-covert filter design transmits more of the near infrared energy. These filters are used with imaging systems requiring greater sensitivity to wavelengths 800-900nm. Typically used with infra-red cameras, scopes,...
Infrared (IR) Blackeye Filters This unique filter consists of a two piece optically coated substrate designed to block the visible output of a light source from as close as 3 feet. Transmittance is ≤1.0%...
