We offers an extensive production line of birefringent crystals for polarization applications. Introduction: Weoffers 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.   Specifications： Wavelength Range Calcite:350-2300nm                         α-BBO: 200-3500nm  Extinction Ratio Calcite:<5x10-5 α-BBO:<5x10-6 Surface Quality 20/10 Dimension Tolerance 0/-0.1mm Beam Deviation          ＜3′ Wavefront Distortion    α-BBO:＜λ/4 @ 632.8nm                          Calcite:＜λ/2 @ 632.8nm       Coating Single layer MgF2 Damage Threshold ＞500MW/cm2 Housing Black Anodized Aluminum         •   High Polarization Purity  •   Wide Wavelength Range •   High Total Transmission   Order Information：  PGT---                                 100    ---                                 CAL ↓                                           ↓                                           ↓ Product Code         Clear Aperture "a"=10mm                    Material   Glan-Taylor Polarizer： Part Number   Wavelength Range （nm）    a （mm）  D （mm）  L±0.1 (mm)  Material PGT-100-CAL 350-2300 10 25.4 18.5   Calcite    PGT-150-ABBO1 15 30 23.0 Calcite PGT-100-ABBO1 200-270 10 25.4 18.5 α-BBO    PGT-150-ABBO2    15 30 23.0 α-BBO PGT-100-ABBO2 400-700 10 25.4 18.5 α-BBO PGT-150-ABBO3 15 30 23.0 α-BBO PGT-100-ABBO3 700-3000 10 25.4 18.5 α-BBO PGT-150-ABBO3 15 30 23.0 α-BBO  Note：Custom designs for other sizes and coatings are also available  upon request.
