Night Vision Enhancement LP900 Longpass Filter
- ModelLP900
- SpecificationCustomizable
- MaterialOptical glass
Description
The LP900 longpass filter is built with multi-layer dielectric coatings achieving deep blocking across the wide 200–875 nm range. It effectively blocks UV, visible and part of the IR light below 900 nm and highly transmits the band above — serving as a receiving optic for pulsed laser bands and enhancing CMOS sensor clarity for industrial inspection and face-recognition security systems. Its steep transition band ensures clean signal/noise separation; in LiDAR and ranging it blocks ambient light for greater detection distance and glare resistance.
