Non-Reflective Neutral Density (ND) Filters

Non-Reflective Neutral Density (ND) Filters are designed to evenly attenuate a light source while preventing unwanted back reflections. A proprietary coating design minimizes reflection to less than 2%, while maintaining high neutrality over the entire designed spectral range. Non-Reflective Neutral Density (ND) Filters feature a B270 substrate and are offered in diameters of 12.5 or 25mm and a 1.5mm thickness. Available for visible applications from 400-700nm or NIR applications from 700-1200nm, the filters are ideal for limiting the transmission of broadband halogen, fluorescent, and tungsten sources, as well as low power lasers. 

Note: Due to supply chain issues, our kits may be delivered with an alternative packaging solution in place of a wooden box. For any questions, please contact [email protected]. 

Non-Reflective Neutral Density Filter Kits

Each kit includes 10 filters in optical density values of 0.3, 0.5, 0.6, 0.9, 1.0, 1.3, 1.5, 2.0, 2.5, and 3.0. The kits are ideal for determining precise system optical density requirements.

Custom densities are available for OEM applications.
