LP900 Longpass Filter
- ModelLP
- SpecificationCustomizable
- MaterialOptical glass
Description
The LP900 longpass filter blocks UV, visible and part of the IR light below 900 nm and transmits wavelengths above 900 nm with high efficiency. It is used as a receiving optic for pulsed laser bands and to enhance CMOS sensor clarity in industrial inspection and face-recognition security systems. Biochemical analysis, Raman spectroscopy, thermal imaging and material research all benefit from its steep transition and deep blocking.
