LP630 Longpass Filter
- ModelLP
- SpecificationCustomizable
- MaterialOptical glass
Description
The LP630 longpass filter transmits light longer than 630 nm and blocks shorter wavelengths. Compared with conventional colored optical glass, it offers a much steeper cut-on, higher transmission and higher background optical density. As the angle of incidence increases, the cut-on wavelength shifts to shorter values, allowing fine tuning of the working wavelength in optical systems. Typical uses include beauty devices, police multi-band inspection instruments, flashlights, stage lighting, optical instruments, fiber illumination and cold-light display cabinets.
