Glan Type Polarizers Telecommunication Application Areas
Product overview:
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.
