850nm High Temperature Resistance Narrow Bandpass Filter, Interference Filter

850nm Narrow Bandpass Filter compatibly used with 850nm LED light or laser light source, which the image sensor only requires a small bandwidth of the 850nm NIR light to for the black and white image.

Available for commonly used IR illumination operating at or around the 850nm wavelengths, BN850 filters feature a narrow band design and is ideal for use when ambient light conditions create poor contrast. Commonly used in security, traffic control, LPR and industrial inspection applications.
