Neutral Density Filters

Used to attenuate, split, or combine beams in a wide range of irradiance ratios, with no significant dependence on wavelength. • Absorptive: Broadband use, attenuation varies with wavelength; low power • Metallic: Broadband use, uniform attenuation with wavelength; low power • Dielectric: Narrowband use, precise attenuation; high laser damage threshold
