Product Description
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. Available in 25.4 mm diameter round or 50.8 mm square sizes.
