Neutral Density Filter Sets

The FR-ND-P UV Fused Silica Metallic Neutral Density Filter Set is a set of eight 1 inch (25.4 mm) diameter UV Fused Silica metallic ND filters, and includes a storage box. 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. Products included in this set are listed below. Please note this set has two FRQ-ND01.
