Introduction：
CASTECH offers an extensive production line of birefringent crystals for polarization applications. Our crystal polarizer family includes Glan-Taylor Polarizers, Glan-Laser Polarizers, Glan-Thompson Polarizers, Wollaston Polarizers, Rochon Polarizers and Quartz Polarization Rotators. Substrate options have α-BBO (UV), calcite (visible to Near-IR), yttrium orthovanadate (YVO4, Near-IR to Mid-IR), MgF2 (UV to Mid-IR), and crystal quartz (UV to Near-IR). Both the mounted and unmounted crystals are available. Contact us freely to select the ideal combination of construction type, substrate, coating design, angle of operation and laser damage resistance level to suit your applications.
