Narrow Bandpass Filters

These filters are narrow bandpass filters to transmit the specified signal/pump wavelength and reject the pump and background wavelengths. Newlight Photonics offers bandpass filters at any wavelength between 340-1064 nm with a very high peak transmission and steep edge slopes for maximum spectral noise rejection.
