0.6 OD 25mm Dia UV-NIR ND Filter

Product Details Constant Transmission from 190 – 1700nm Can be Stacked to Create Intermediate Density Values Multiple Optical Densities Available TECHSPEC UV-NIR Neutral Density (ND) Filters are used to attenuate light from the ultraviolet to the near-infrared. TECHSPEC UV-NIR ND Filters feature excellent parallelism with superior surface characteristics to provide constant, ultra-broadband performance from 190 – 1700nm. These ND filters are ideal for a range of applications including spectroscopy, machine vision, or ellipsometry, or for use with low power lasers. TECHSPEC UV-NIR Neutral Density (ND) Filters can be stacked to obtain a range of optical densities. Note: UV-NIR Neutral Density Filter kit includes all optical densities. Filter coating is fragile and should be handled with care. Use non-contact cleaning methods only.
