BN660 Narrow Dark Red Bandpass Filter
Narrow Dark Red Bandpass Filter for machine-vision imaging — passes 645-675nm and blocks out-of-band light for repeatable contrast on the line.
Overview [ 01 ]
Commonly used in outside applications bothered by intense sunlight, BN660 filters are suitable for use with 660-670nm laser diodes and LED lighting, and are less sensitive to angle of incidence variations than traditional interference filters.
* Not available in 1mm thickness or standard 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. To view this alternative C-Mount option, click here .
