Longpass Edge Filter Set, 25.4 mm, Includes 13 Edge Filters and Case

The FS-LWF-B Longpass Edge Filter Set includes 13 of our 25.4 mm diameter long-pass filters with cut-on wavelengths ranging from 450 to 1000 nm and a hardwood case. Our long-wave pass filters have a steep transition between the region of transmission and reflection that is much steeper than colored glass longpass filters. Long-wave pass filters have out-of-band rejection =OD 3 to X-ray. Typical transmission is =80%. These optical filters are available individually. Products included in this set are listed below.
