Shortpass edge filters
Shortpass edge filters allow shorter wavelengths to pass through (with transmissivity oftentimes over 90%), whereas they attenuate or reflect longer wavelengths. Solaris Optics manufactures filters within UV to near IR.
Shortpass filters are specified primarily by an edge wavelength, a cut-off wavelength, which defines the spectral point after which the light is blocked.
A basic list of specifications a shortpass filter 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 shortpass filters.
