Description

 

The 10LWF-400-B Dielectric Longpass Edge Filter is a 1 inch (25.4 mm) diameter optical filter with a 400 ±5 nm cut-on wavelength and a 410 to 1200 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%.
