High extinction ratio infrared
polarisers
All the polarisers give no beam deviation problems and have extremely good surface uniformity and flatness that stray light problems are virtually eliminated
Infrared polarisers made by holographic and laser controlled ruled methods are available from Medway Optics at very high value-to-cost ratios These polarisers produced on different substrates including calcium fluoride, barium fluoride, zinc selenide, KRS-5 and polyethylene allow unlimited choice for polarisation applications from 1 to 250 microns in a variety of sizes

Polarised heat
Infrared and far-infrared polarisers for applications including material synthesis characterisation, identification, spectroscopy, microscopy, and interferometry astronomy
All the polarisers give no beam deviation problems (encountered with Brewster angle and prism polarisers) and have extremely good surface uniformity and flatness that stray light problems are virtually eliminated.
Additionally, the holographic polarisers give high extinction and contrast ratios and, with optional anti-reflection coating, exceptional transmission and polarisation efficiencies are achieved.
The laser controlled ruled polarisers have high laser damage thresholds, typically 100watts/cm2CW.
Numerous applications of these polarisers include material synthesis characterisation, identification, beam attenuation and separation in spectroscopy, microscopy, ellipsometry, thermal imaging, laser instrumentation, astronomy and in R and D.
