UVFS Linear Variable Metallic ND Filter Pair, 79.4x25.4mm, 0.08-2 OD

The 31Y02MP-ML.1 Matched Filter Pair is a matched pair of Linear Variable Metallic ND Filters, made of UV grade fused silica, dimensions of 79.4x 25.4 mm, with an OD of 0.08-2, and surface flatness of ≤1λ. These ND filters provide linearly varying attenuation or beam splitting in the visible and NIR region. Attenuation is achieved by a thin film of aluminum protected with an overcoat, and variable beam splitting is an added benefit of the inherent reflectivity of aluminum. The BK 7 or UV fused silica substrates have a slight wedge between the faces to eliminate unwanted fringe patterns and cavity feedback, and the rear surface is also antireflection coated for the broadband visible range.
