BN740 Narrow Near-IR Bandpass Filter
Narrow Near-IR Bandpass Filter for machine-vision imaging — passes 730-755nm and blocks out-of-band light for repeatable contrast on the line.
Overview [ 01 ]
One of the commonly used IR illumination wavelengths, BN740 filters are suitable for laser diode and LED applications. The narrow band design is ideal when there are overwhelming ambient light conditions. Commonly used in security, traffic control and industrial inspection applications.
