A Glan–Taylor prism is made of two birefringent wedges which are separated on their long surfaces with an air gap. By arranging optical axes parallel to the plane of entrance, total internal reflection of s-polarized light at the air-gap ensures that only p-polarized light is transmitted by the device. Because the incident angle at the gap can be reasonably close to Brewster's angle, a considerable increase in transmission is obtained. The Glan–Taylor prism does not have escape windows and it is suitable for low to medium power applications
You may refer to this page (http://www.pmoptics.com/crystals.html) for material properties.
