BN785 Narrow Near-IR Bandpass Filter
Narrow Near-IR Bandpass Filter for machine-vision imaging — passes 770-790nm and blocks out-of-band light for repeatable contrast on the line.
Overview [ 01 ]
For use with 780-785nm IR illumination wavelengths, including LED and laser diode lighting, the narrow band design is ideal for use when ambient light conditions can be overwhelming. Commonly used in traffic control, security and license plate recognition applications.
