Glan-laser polarizers are air-spaced, select-grade calcite prism pairs with the prism interface angles optimized for minimum insertion loss. They can be used in Q-switched laser cavities and other multiple pass applications. The housing mounts into our standard 25.4 mm holders, and the polarizers are offered with broadband AR coatings for the visible and NIR regions or a special V-coating for 1064 nm.
