Pumped for industrial, medical, and biological sciences instrumentation, the company’s infrared narrow bandpass (IR NBP) filters offer high spectral performance with accurate center wavelength placement, and reliable temperature stability. The NBP filters’ IR spectral range enables the detection of a particular gas and to identify the concentration level. The filters are calibrated for center wavelength placement to offset temperature shifts. They also feature reliable and repeatable transmittance characteristics.
