LP680 Longpass Filter
- ModelLP
- SpecificationCustomizable
- MaterialOptical glass
Description
The LP680 longpass filter provides high transmission above 680 nm and effective blocking below. It features steep cut-on slope, high transmission and high background optical density; the cut-on wavelength shifts toward shorter wavelengths as the incidence angle increases, enabling system-level wavelength tuning. Uses include infrared imaging and thermal cameras, fluorescence and Raman spectroscopy, and semiconductor material characterization.
