Neutral-density optical filter
Bookham
Neutral density (ND) filters are used to attenuate the intensity of a light beam. Metallic neutral density filters provide a relatively consistent degree of attenuation over a wide spectral band. We offer a variety of catalog ND filters for UV/VIS applications including absorptive, metallic on glass or fused-silica, and variable linear or circular, as well as filters for infrared applications.
