BN850 Narrow Near-IR Bandpass Filter
Narrow Near-IR Bandpass Filter for machine-vision imaging — passes 840-865nm and blocks out-of-band light for repeatable contrast on the line.
These filters are available for use in conjunction with commonly used IR illuminators operating at or around the 850nm wavelength. BN850 filters feature a narrow band design that is ideal for use when ambient light conditions create poor contrast. They are commonly used in security, traffic control, LPR and industrial inspection applications.
* Not available in 1mm thickness or 25.4™ C-Mount option. For filters thicker than 1mm, we offer an alternative mounting solution that has an overall thickness of 5.5mm. This mount can accommodate filters up to 3.5mm thick. For this alternative C-Mount option, click here .
