MidOpt BN660-55 Narrow Bandwidth Dark Red Bandpass Filter

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 with an overall thickness of 5.5mm. This mount can accommodate filters up to 3.5mm thick.
