Glan-Taylor prism

Polarized light for UV-VIS-NIR measurements is often produced using a Glan-Taylor prism. The total reflectance for s- R ) and p-polarized (Rp)... 

The reflectance and PR measurements of samples I-II and samples IV-VI, respectively, were carried out at near normal incidence between 6 and 10 K and at 295 K. For the PR measurements, the pump beam at 300 nm (4.13 eV) was obtained from a combination ofa 150 W Xe lamp with a 1-m monochromator, while the beam for both the reflectance and PR probe was derived by dispersing the light from a 75 W Xe lamp with a 0.64-m monochromator and polarizing it with a Glan-Taylor prism. The reflected light was detected by a silicon photodiode using standard lock-in techniques. 

A convenient way to attain a very high degree of linear polarization is to use prisms made of the birefringent material calcite (CaCOs). The arrangements in Glan-Taylor and Glan-Thompson polarizers are shown in Fig. 6.46. Both these polarizers consist of a combination of two prisms, in the first type air-spaced, in the second case cemented. The prism angle has been chosen such that the ordinary beam is totally internally reflected and absorbed laterally in the prism, while the extraordinary beam is transmitted into the...
