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   ·  Extinction ratio: 100,000:1   ·  Standard and custom coating options available   ·    · High laser damage threshold   Specifications：  Material Calcite；α-BBO Wavelength Range Calcite: 350-2300nm                         α-BBO: 220-900nm Extinction Ratio  Calcite:<5x10-5 α-BBO:<5x10-6 Surface Quality 60/40 Dimension Tolerance ±0.1mm Damage Threshold ＞200MW/cm2 Beam Deviation          ＜3′ Wavefront Distortion ＜λ/4 @ 632.8nm Coating Single Layer MgF2 Housing Black Anodized Aluminum       •  •    Large Acceptance Angle: Special design for the ratio of  l/A (length/aperture) guarantees the wide acceptance angle.    •   High Polarization Purity.   •   Suitable for low power applications.
