Contact our applications experts to define the product that will provide the best performance for your application. Short and Long-Wave Pass Filters Our short and long-wave pass filters have a steep transition between the region of transmission and reflection — much steeper than colored glass filters. Both the short and long-wave pass filters have out-of-band rejection OD 3 to X-ray (for LWP) and to 1200nm (for SWP). Typical transmission is 80% for long-wave pass and 65% for short-wave pass filters. These filters are available individually and in sets.
