Broadband DUV Polarizer (190-3300nm)

FOCtek Patent No.:ZL2005 1 0018753.6

Broadband Glan Thompson Polarizer is made of two α-BBO prisms cemented together. Unlike other types of α-BBO polarizer and Calcite Polarizer which are used from about 190 nm to 900 nm and 350 nm to 2300 nm respectively, this broadband polarizer has a wide rang of wavelength from 200nm to 3300nm. Also the broadband polarizer has a wide acceptance angle whose field angle Fo and Fe is shown in below figure.
