Glan-Taylor polarizer 2-G series

high-power

Glan-type polarizers are mounted polarizing prisms used for applications that require broad spectral ranges, high extinction ratios and/or high polarization purities. A typical use for such polarizers is for “cleaning” the polarization of a light source, or for the attenuation of a polarized light source. Glan-type polarizers have a few advantages over thin film polarizers (TFPs): firstly, the extinction ratio of Glan-type polarizers is higher than that of TFPs by 2 to 4 orders of magnitude, allowing them to have better polarization purity; secondly, they have a broadband spectral operation range, whereas TFPs are designed for narrow laser-line operation. Standard Glan-type polarizers are mounted into barrel type mounts, which are convenient for most applications. Altechna offers three types of Glan-type polarizers, you can choose according to your application: - Glan-Taylor - Glan-laser - Glan-Thompson Material α-BBO, YVO4, Calcite Wavelength range 200 – 4000 nm Clear aperture Ø8 – 20 mm Length 15 – 50 mm Extinction ratio <5×10-6* Surface quality, S-D 20-10 Transmitted wavefront distortion, P-V 100-500 MW/cm²
