Glan-Taylor Calcite Air Spaced Polarizer GT15
Description
The Glan-Taylor design produces a high extinction ratio polarizer with low reflection losses and a high power handling capability. It is therefore particularly useful for polarizing laser light, with the further advantages that there is no transmission deviation or offset, and that a wide spectral range can be polarized. LEYSOP supplies GT model Glan-Taylor polarizers with apertures from 10-20mm and larger to special order. Side faces are fine ground as standard, which is adequate to disperse the internally reflected polarization state. Polished side exit faces are provided if required and are recommended for all high power applications. The standard interface angle makes the polariser suitable for operation across a wide wavelength range. Other interface angles can be ordered to cover requirements across the full transmission range of calcite from 0.2 - 2.5µm. please note that because of the absorption in calcite, transmission for most Glan-Taylor polarizers is reduced below 350nm. The main optical surfaces are polished to a flatness of better than l/8 at 0.63µm. Please be aware though that side exit faces are not able to be polished to this same high specification because of the weakness of this face in calcite.
