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.

| 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... | |
| 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. | |
| 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... | |
| 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... | |
| 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,... | |
| 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%... |
