Longpass edge filters
Longpass edge filters allow longer wavelengths to pass through (with transmissivity oftentimes over 90%), whereas they attenuate or reflect shorter wavelengths. Solaris Optics manufactures longpass edge filters within UV to near IR.
Longpass filters are specified primarily by an edge wavelength, a cut-on wavelength, which defines the spectral point after which the light is passed.
A basic list of specifications of longpass edge filters include:
- cut-on wavelength
- overall working spectral range,
- minimum required transmission in the pass range,
- rejection level (in OD).
Other relevans specs include:
- shape and physical dimensions,
- suface quality.
We are happy to discuss your needs for longpass filters.
