Products Description

BP14500 Bandpass Filter | 1000nm FWHM, >70% Transmission, OD2 Blocking

The BP14500 is a precision infrared bandpass filter engineered for demanding atmospheric sensing and trace gas detection applications, where accurate spectral isolation directly impacts measurement reliability. Featuring a center wavelength of 14500nm with ±50nm tolerance and a 1000nm full-width at half-maximum (FWHM), this filter delivers high transmission efficiency of over 70% within the passband, maximizing signal throughput for weak infrared detection.

It provides consistent optical density performance of greater than OD2 across the 400nm to 19000nm range, effectively suppressing background noise and unwanted ambient radiation. Manufactured with advanced thin-film coating technology on premium infrared substrates, the filter delivers excellent spectral uniformity and long-term stability under varying operating conditions. As part of OPTOStokes’ comprehensive bandpass filters portfolio, it meets strict precision requirements for industrial and scientific optical systems.
