Products Description
BP970 Bandpass Filter | CWL 970nm, FWHM 10nm
The OPTOStokes BP970 narrowband optical filter is engineered for high-precision near-infrared (NIR) applications where tight spectral selectivity and superior signal-to-noise ratios are paramount. Featuring a peak center wavelength (CWL) of 970 ± 2nm and a narrow full-width at half-maximum (FWHM) of 10 ± 3nm, this optical filter isolates desired spectral bands while attenuating unwanted background radiation. As part of our high-performance bandpass filters series, it provides optimal throughput for sensitive optical sensing and imaging systems.
