OD5 Reflective Neutral Density Filter (T=0.001%, 190-2600nm)

This OD5 reflective neutral density filter provides T=0.001% nominal transmission across 190 nm to 2600 nm. It is suitable for laser power control, broadband light attenuation, imaging, spectroscopy, and optical measurement systems that need stable intensity reduction across UV, visible, and near-infrared wavelengths. The reflective ND coating attenuates by reflection rather than absorption, helping manage optical power in broadband setups.
