Glan-Taylor Polarizers produce extremely pure linear polarization with an extinction ratio greater than 100,000:1 and are meant for use with laser beams in the 350 nm – 2.3 μm wavelength range. A significant amount of reflected light escapes the polarizers through the side port, including all of the ordinary ray and some of the extraordinary ray. As such, the escape beam is not fully polarized, and only the transmitted extraordinary ray should be used for applications that require a high-quality, polarized beam.
