Metallic-coated infrared neutral density filters

INFRARED NEUTRAL DENSITY FILTERS | IR ND FILTER KITS 

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 infrared neutral density filters exhibit outstanding spectral neutrality, outperforming all others on the market.

We also have a new variant available for select densities which includes a broadband anti-reflective coating on one side. This is useful in imaging systems where multiple reflections from the coated surfaces could be a concern. Look for BBAR in the part number.

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