Product Family Description

  • Optical Densities from 0.1 to 4.0
  • VIS 0°, NIR I, and NIR II Coating Options
  • 12.5, 25, and 50mm Diameter Sizes
  • Uncoated HOYA or SCHOTT ND Filters Also Available

Anti-Reflection (AR) Coated HOYA Absorptive Neutral Density (ND) Filters feature HOYA colored glass substrates that are AR coated on both surfaces to reduce back reflections in the visible or near-infrared (NIR) spectra. VIS 0°, NIR I, and NIR II broadband AR coatings cover the spectral ranges of 425-675nm, 600-1050nm, and 750-1550nm. These neutral density filters attenuate light via absorption and can be stacked together to achieve custom optical densities to meet application requirements. Anti-Reflection (AR) Coated HOYA Absorptive Neutral Density (ND) Filters are ideal for use in imaging and detection applications to reduce stray light, as well as in general filter stacking applications to control intensity. The standard metric diameters of 12.5, 25, and 50mm are compatible with our TECHSPEC® C, S, and T-Mount Circular Optic Mounts for benchtop applications.
