Knight Optical’s Mica Retarders for Optical Systems | |
11 Nov 2022
Knight Optical supplies a wide-ranging portfolio of Mica Retarders suitable for a range of applications – including optical systems. These Retarders are available as custom-made optical components or from stock for next-day dispatch (please note, our stock range is being discontinued). Our Mica Retarders are manufactured from a thin layer of a fragile birefringent material, which is then sandwiched between two glass plates. As such, they are used to change the polarisation of incident light and output different polarised light with minimal attenuation. What's more, they can be used to isolate polarised light to remove feedback and, in conjunction with a Beamsplitter, may be used to route light more efficiently. Typical specs: Material: N-BK7 (or equivalent) [window], Mica (retarder) Diameter tolerances: +/- 0.1mm Thickness tolerances: +/- 0.1mm Quarter wave: +/- 0.01λ Half wave: +/- 0.02λ Parallelism: +/- 5 arcminutes Surface figure: < 2 waves Surface quality: < 20-10 Scratch/Dig Coatings: < Antireflective (AR) Coatings available on request First-Class Quality Quality is the driving force behind Knight Optical, and to ensure you profit from high-precision optics, we take the utmost care to ensure every component accurately meets your specifications.
