Glan-Taylor Polarizer

Glan-Taylor PolarizerGlan-Taylor Polarizer is assembled of two same birefringent crystal prisms with an air space(no glue). It has no escape window is suitable for low to medium power applications where the rejected beam is not required. It has a length to aperture ratio less than 1.0 makes it a relatively thin polarizer.
