Metallic ND Filter, UV Fused Silica, 25.4 mm, 1.0 OD at 632.8 nm
Model: FRQ-ND10
Product Series Overview
UV Fused Silica Metallic ND FiltersThe FRQ-ND10 UV Fused Silica Metallic Neutral Density Filter is a 25.4 mm diameter UV Fused Silica Metallic ND Filter with an optical density of 1.0 at 632.8 nm. Our metallic neutral density coatings provide broadband attenuation for lower power applications. The coating is deposited on one side of an ultra-pure UV grade fused silica substrate providing excellent transmission from the UV to near-infrared. All filters are permanently marked with the optical density.
