Edmund Optics Inc. OD 2.0 NIR Non-Reflective ND Filter, 25mm Dia NT63-413

Prevent Unwanted Reflection Towards the Light Source Spectrally Flat VIS and NIR Ranges Available Our Non-Reflective Neutral Density 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 very high neutrality over the entire design spectral range. 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. TECHSPEC® 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.
