Neutral Density Filter, Infrared, 25 mm, 0.5 OD, ±2.00% Tolerance

The NDIR10-05 Infrared Neutral Density Filter is a 1 inch (25.0 mm) diameter filter with an optical density of 0.5, and ± 2% transmittance tolerance. Optimized for 2 to 5 μm, this filter attenuates IR radiation from 2 to 14 μm. It is made from a germanium substrate and is coated with a spectrally neutral vacuum deposited metal alloy reflective coating.
