Edmund Optics Inc. 1.3 Optical Density 12.5mm Diameter UV-VIS ND Filter NT48-621

Ideal for 200-700nm Sources Optical Densities Ranging from 0.3 to 3.0 Our TECHSPEC® UV-VIS reflective neutral density (ND) filters are spectrally flat from 200 to 700nm and feature outstanding parallelism and surface characteristics. This combination of high tolerance and broadband performance makes these filters ideal for attenuating a wide range of sources. The filters are suitable for low power laser applications and can be stacked to obtain a variety of optical densities. Orient mirrored side toward source at 0° angle of incidence. Optical Densities of 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 available in a Pre-Loaded Filter Wheel. TECHSPEC® UV-VIS Reflective Neutral Density Filter Kit Each kit includes 8 filters in optical density values of 0.3, 0.5, 1.0, 1.3, 1.5, 2.0, 2.5, and 3.0. The kit is ideal for determining precise system optical density requirements. Custom densities are available for OEM applications.
