Bandpass Filter Selection Guide

Bandpass filters isolate a band of wavelengths from the total spectrum by providing a band of high transmission and bands of high rejection of spectral energy on both the long and short wavelength sides of the transmission band. We make catalog and custom bandpass filters over the range of 200 nm to 16 µm with bandwidths ranging from 0.3nm in the UV/VIS to as wide as 4µm in the IR.
