• Introduction：

Barium metaborate (α-BBO) crystal is an excellent birefringent material with very good optical properties and good transmission from ultraviolet to mid-infrared. α-BBO crystals have good internal quality, and low absorption, and because of their good UV transmission, they are widely used in high extinction ratio and deep UV lamp systems: Glan prisms, and polarizing beam splitters.
