Products Description
895nm Narrow Bandpass Filter | FWHM 30nm, 1.1mm Thickness
The OPTOStokes 895nm narrow bandpass filter is engineered for high-precision near-infrared (NIR) signal isolation. Delivering greater than 90% peak transmittance across the 885–905 nm passband combined with reliable OD2 blocking (T < 1%) from 350 to 1100 nm, this component effectively eliminates out-of-band background noise. It serves as an ideal optical solution for LiDAR sensing, laser rangefinding, and NIR imaging applications requiring uncompromising signal-to-noise ratios.
