格兰偏振棱镜
Their properties are similar to Glan-Taylor polarizer. The Glan-Laser polarizers are constructed of a superior grade of two same birefringent material prisms that is chosen to minimize beam scatter and distortion. These crystal ensure the polarizer to withstand much higher laser power densities than the Glan-Taylor series. Therefore, they are suitable for high power applications.
