Glan Taylor Polarisations
 |
Glan Taylor Polarisations besteht aus zwei gleichen Birefringence Material Prismen, die mit einem Luftraum montiert werden. It has a length to aperture ratio less than 1.0 makes it a relatively thin polarizer. The polarizer with no side escape windows are suitable for low to medium power application where the side rejected beams are not required. The angular field of different materials of polarizers is listed below for comparison. |
