This special version of the Glan-Taylor polarizer is cut such that the P-polarization (extra-ordinary ray) intersects all four optical faces at Brewster's angle, thus ensuring a minimal insertion loss over a wide operating wavelength range. Transmission in fact is approaching 99% for the P-polarization and extinction ratio is exceptional, exceeding that of the more conventional cut Glan-Taylor.
One disadvantage of the Brewster cut Glan-Taylor polarizer, as you can see from the above diagram, is that it produces a reasonably large offset in the beam line. This is typically around 5 to 7mm depending on the size of the device and because of the refraction at the Brewster interfaces, it is also wavelength dependent.
Nominally available apertures are 8, 10 or 12mm and the polarizer can be supplied in a mount if required. As always, Leysop are happy to discuss your precise requirements for these and other components so please contact us.
