Band-Pass Filters

Superior Spectral Selectivity

Our band-pass filters offer exceptional spectral selectivity with customizable bandwidths from a few nanometers to hundreds of nanometers. Essential for applications in spectroscopy, chemical analysis, laser applications and multispectral imaging.

Designed with high-precision multi-layer deposition technologies, they guarantee high transmission in the pass band and high reflection in adjacent bands. Thermal stability and durability ensured for critical operating environments.
