Bi832 Near-IR Interference Bandpass Filter
Near-IR Interference Bandpass Filter for machine-vision imaging — passes 822-846nm and blocks out-of-band light for repeatable contrast on the line.
Overview [ 01 ]
These filters are available for use in conjunction with commonly used IR LED or laser diode illuminators operating at or very close to the 830nm wavelength. Our new Bi832 filters feature a much narrower band design that is ideal for use when ambient light conditions might otherwise create unacceptable contrast. They can be useful in night vision, security, traffic control, LPR and industrial inspection applications.
