Calcite Glan-Laser Polarizer

We offers an extensive production line of birefringent crystals for polarization applications.   Introduction: We 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.   Features: Material: Calcite, α-BBO, YVO4, MgF2 or Crystal Quartz   Custom dimension and shapes   Diameter from 5 to 25.4 mm   Extinction ratio: 100,000:1   Standard and custom coating options available   High laser damage threshold     Specification： Wavelength Range Calcite: 350-2300nm         α-BBO: 190-3500nm Extinction Ratio Calcite:<5x10-5 α-BBO:<5x10-6 Surface Quality 60/40 Dimension Tolerance  ±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   Order Information：     PGL --- 100 --- CAL ↓   ↓   ↓ Product Code    Clear Aperture "a"=10mm   Material Code     Glan-Laser Polarizer： Part Number   Wavelength Range （nm）   a （mm） D （mm）   L±0.1 (mm)  Material PGL-100-CAL 350-2300 10 25.4 26.2    Calcite    PGL-150-CAL 15 30 33.3 Calcite PGL-100-ABBO1 200-270 10 25.4 31.0 α-BBO PGL-150-ABBO1 15 30 38.6 α-BBO   PGL-100-ABBO2   400-700 10 25.4 26.0 α-BBO PGL-150-ABBO2 15 30 33.4 α-BBO PGL-100-ABBO3 700-3000 10 25.4 25.9 α-BBO PGL-150-ABBO3 15 30 33.0 α-BBO    Note：      •   Custom designs for other sizes and coatings are also available upon request.      •   YVO4 Glan-Laser Polarizer is also available  upon request.
