Neutral Density Filter Sets

The FB-ND-P Optical Crown Glass Metallic Neutral Density Filter Set is a set of eight 1 inch (25.4 mm) diameter optical crown glass metallic ND filters of various optical density, and includes a storage box. 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. Products included in this set are listed below. Please note this set has two FBR-ND01.
