Product Family Description

  • Spectrally Flat from 2μm to 14μm
  • Precision Germanium Substrate

Our IR Neutral Density Filters feature excellent linearity over a wide spectral band of 2μm to 14μm. Ideal for thermal and medical imaging, the filters are available in a variety of densities and 2 size options. Attenuation is achieved by a metal alloy coating, which employs a combination of absorption and reflection to achieve the stated transmittance value. All 5 optical densities are available as part of our Neutral Density Filter Kits. The kits are ideal for integration with our filter wheels.

Please contact our Applications Engineering Department to discuss custom size and density options.
