IR materials

Germanium optics for Thermal coreKnight Optical’s infrared optical materials are used in a wide range of applications such as thermal imaging systems used in the oil and gas industry to identify gas leaks quickly.

We also supply components for infrared sensors for engineering and industrial manufacturing and in thermography, where infrared radiation is detected and mapped.

Substrates such as Barium Fluoride are used in the Fuel oil industry and Germanium and Sapphire are tough subsrates which can withstand extreme environments.

Our extensive choice of infrared materials is available as:

  • Polished blanks
  • Windows
  • Lenses
  • Aspherics
  • Prismsd
  • Rods

Our infrared optical components benefit from anti-reflection and hard coatings, optimised for your specifications, with DLC for 3 – 5 micons and 8 – 12 microns and AR coatings for custom wavelength bands and multiwavelengths.

Knight Optical’s Infrared capabilities are designed with exact specification compliance in mind. Custom specifications of dimensions, focal lengths and tolerances are quoted on an individual basis.  If you can’t find what you are looking for in our stock items please contact us for a custom quote.
