Diameter: M40.5 x P0.5
The MidOpt BN850-40.5 filter is for use with commonly used IR illuminators operating at or around 850nm. 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. All MidOpt filters can also be purchased unmounted or in custom dimensions upon request from Machine Vision Direct.
