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. Please see spare parts list below for the included edge filters.

该FS-LWF-B长通边滤波器组包括13个我们的25.4毫米直径的长通滤波器，具有从450至1000纳米的切割波长和一个硬木外壳。我们的长波通滤波器在透射和反射区域之间有一个陡峭的过渡，比彩色玻璃长波通滤波器陡得多。长波通滤波器对x射线有带外抑制=OD 3。典型的传播率是=80%。这些滤光片可以单独使用。请参阅下面的备件清单所包含的边缘过滤器。
