Mica Retarders

Due to its close to perfect basal cleavage, custom mica retarders can be made at a much lower cost than their quartz counterparts. We offer AR coated or uncoated glass laminated Mica, but can also supply bare mounted Mica where required.

One may require a quarter-wave plate if they needed to convert linear polarisation to circular, or a half-wave plate to change the direction of linear polarisation. Quarter wave plates could be used alongside a linear polariser in order to stop light reflected from outside surfaces whereas a variable-ratio beam splitter can be made should you combine a half wave plate with a polarising beam splitter cube.

Knight Optical can provide unlaminated mica with special wavelengths, AR coatings, special sized retarders, and also more specialist full wave retardations.

Knight Optical supply high quality custom mica retarders made to our exact specification. Every component is individually tested in our state-of-the-art metrology laboratory by our highly skilled technicians to ensure all components meet our high quality standards.
