Shortpass Filter, Dichroic, 25.0 mm, 400 nm Cut-off, 325-385 nm Transmission

The 10SWF-400-B Dichroic Shortpass Edge Filter is a 0.98 in. (25.0 mm) diameter 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.
