Longpass Filter, Dielectric, 25.4 mm, 400 ± 5 nm Cut-On, 410 - 1200 nm

1 inch (25.4 mm) dielectric coated bandpass filter

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%.
