Products Description
BP940nm Bandpass Filter | FWHM 10nm, OD2 Blocking
The OPTOStokes BP940nm bandpass filter is designed for near-infrared 3D imaging and optical sensing systems operating around the solar-absorption dip. Delivering over 90% peak transmission at 940nm combined with an ultranarrow 10nm spectral bandwidth, this filter blocks ambient room light and solar radiation to increase optical signal contrast. OPTOStokes provides extensive stock availability and flexible custom optical coatings to accelerate your production cycles.
