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.
