Description

 

The 10LWF-1000-B Dielectric Longpass Edge Filter is a 1 inch (25.4 mm) diameter optical filter with a 1000 ±7 nm cut-on wavelength and a 1020 to 2200 nm transmittance range. Long-wave pass filters have a steep transition between the region of transmission and reflection that is much steeper than colored glass filters. Longpass filters have out-of-band rejection ≥OD 3 to X-ray. Typical transmission is ≥80%.
