Infrared Neutral Density Filters for Thermal Imaging

IR NEUTRAL DENSITY FILTERS

Metallic-coated infrared neutral density filters (IR ND filters) obtain their optical density from a metal alloy coating on a substrate determined by the wavelength region of interest. Unlike the all-dielectric or absorption type, the metallic type ND filter employs a combination of absorption and reflection to reduce the intensity of light. 

Andover's IR ND filters exhibit outstanding spectral neutrality, outperforming all others on the market.  

Note: Custom sizes and spectral characteristics are available on request. Contact our technical sales department for a quotation.

  • Provides attenuation with greater linearity over a wide spectral range
  • Delivers superior durability
  • Custom substrates available
COMMON APPLICATIONS
  • Thermal imaging
  • Medical imaging
  • IR test bench
