BP4680-150 MWIR Bandpass Filter | FWHM 150nm, CO Sensing

BP4680-150 MWIR Bandpass Filter | FWHM 150nm, CO Sensing

The BP4680-150 is a precision mid-wave infrared (MWIR) optical component designed for demanding non-dispersive infrared (NDIR) and spectroscopic gas sensing applications. Featuring a center wavelength (CWL) of 4680 +/- 30 nm and a full width at half maximum (FWHM) of 150 +/- 20 nm, this high-performance bandpass filter achieves high peak transmission (T > 80%) while maintaining deep out-of-band blocking (OD > 2 from 400 to 11000 nm) to maximize optical signal-to-noise ratio.

Technical Specifications

Applications
