The 10SWF-500-B Shortpass Edge Filter is a 1 in. (25.4 mm) diameter optical filter with a cut-off wavelength of 500 ±5 nm, and transmittance of 415-490 nm. Our short-wave pass filters have a steep transition between the region of transmission and reflection that is much steeper than colored glass filters. Shortpass filters have out-of-band rejection ≥OD 3 to 1200 nm. Typical transmission is ≥65% for short-wave pass filters. These optical filters are also available as part of the FS-SWF-B shortpass filter set.
