BP1555nm Bandpass Filter | CWL 1555nm, FWHM 25nm

The OPTOStokes BP1555nm bandpass filter is precision-engineered for high-performance Short-Wave Infrared (SWIR) systems. Optimized for an Angle of Incidence (AOI) of 0 degree, this specialized filter delivers a peak transmission where CWL is 1555nm ± 2nm (T > 85%), with an extended transmission spectral window spanning 1500-1560nm at T > 90%. Featuring a narrow Full Width at Half Maximum (FWHM) of 25nm ± 2nm, it isolates precise wavebands while maintaining an average optical density of ODave > 3 across the 350-1700nm spectrum to suppress unwanted out-of-band noise.
