4Lasers provide air-spaced Glan-Taylor and Glan-laser type polarizers fabricated from α -BBO (UV), calcite (VIS to NIR), YVO4 (VIS to Mid-IR) birefringent crystalline material and mounted in a barrel-type black anodized aluminum mount. Glan-type polarizers are constructed to transmit only the extra-ordinary polarized beam, while the ordinary polarized beam is deflected. These polarizers feature an extremely high extinction ratio over a wide wavelength range and their common applications include polarization separation, polarization cleaning, power attenuation. Glan-Taylor polarizers are designed for low and mid-power applications, while Glan-Lasers – for high-power regimes due to their higher damage threshold and escape window in housing for the deflected ordinary polarized beam. A single MgF2 layer is applied to Glan-type polarizer optical surfaces in order to noticeably maximize their broadband transmission.
