Medway Optics Limited offers infrared and far-infrared polarisers made by holographic, laser controlled ruled and precision mechanically ruled methods for diverse applications. These polarisers produced in a variety of sizes on different substrates including Calcium Fluoride, Barium Fluoride, Zinc Selenide, KRS-5 and Polyethylene for use from 1-250µm and free standing tungsten wires for use from 20-2000µm allow unlimited choice for polarisation applications.

All the polarisers give no beam deviation problems common with other types of polarisers. They have extremely good surface uniformity and flatness that stray light problems are virtually eliminated. Additionally, our holographic polarisers give high extinction and contrast ratios and, with optional anti-reflection coating, exceptional transmission and polarisation efficiencies are achieved. Our laser controlled ruled polarisers have high laser damage thresholds, typically 100 watts/cm sq CW and free standing tungsten wires have gold plated option for extreme environment durability .

Numerous applications of these polarisers include material synthesis characterisation, identification, beam attenuation and separation in spectroscopy, microscopy, ellipsometry, thermal imaging, laser instrumentation, interferometry astronomy and in R & D.
