Infrared Polarisers


Knight Optical is able to supply custom optics for use in the IR (1to 20µm) wavebands. The optical polarizers that are available to custom order, range include:

The polarisers are used to divide the s and p beams from the input beam. This is achieved by a, for example, thin film coating on a suitable substrate that reflects the s beam and transmits the p beam. Separation can also be achieved by the use of suitably shaped prisms, such as Wollaston or Rochon arrangement. Wire grid polarisers are used for the wide bandwidth of 2-30µm. The wire grid polariser is ideal for high -energy lasers

Knight Optical supply high quality Polariser optical components made to your exact specification. Every component is individually tested by our highly skilled technicians in our state of art metrology lab to ensure all components meet our high quality standards.
