ND Filter, Metallic, Optical Crown Glass, 50.8 x 50.8 mm, 1.0 OD

The FBS-ND10 Metallic Neutral Density Filter is a 50.8 x 50.8 mm square Optical Crown Glass Metallic ND Filter with an optical density of 1.0 at 632.8 nm. Our metallic neutral density coatings provide broadband attenuation for low power applications. The coating is deposited on one side of a cost effective B 270 optical glass substrate, providing excellent performance in the visible and near-infrared.
