Shortpass Filter, Dichroic, 12.5 mm, 400 nm Cut-off, 325-385 nm Transmission

The 05SWF-400-B High Performance Shortpass Edge Filter is a 0.49 in. (12.5 mm) diameter optical filter with a cut-off wavelength of 400 ±2 nm. Designed for 45 degree angle of incidence beams, it transmits 325-385 nm spectral range and rejects 420 - 485 nm spectral range by reflection. Our short-wave pass filters have a steep transition between the region of transmission and reflection that is much steeper than colored glass filters.
