Blocking Optical Filter, UVB and UVC, 3.0 in. Diameter

The 81050 UVB/C Blocking Filter is a 3 inch diameter optional filter to shape the spectral output of our 1000 W UV Flood Sources (simulators) or SOL-UV series. This filter acts to block wavelengths below 320 nm, effectively transmitting only UVA wavelengths. This filter fits into a solar simulator's integral filter holder, and includes a convenient pull handle which allows for quick and easy insertion and removal of the filter.
