The FS-ND UV Fused Silica Metallic Neutral Density Filter Set is a set of eight, 50.8 x 50.8 mm square, UV Fused Silica Metallic ND Filters. 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. The SR-ND Set includes the following eight filters and a wood case: FSQ-ND003, (2) FSQ-ND01, FSQ-ND03, FSQ-ND05, FSQ-ND10, FSQ-ND20, and FSQ-ND30.
