Glan laser polarizer

Glan Laser Polarizers æ ¼å…°æ¿€å…‰æ£±é•œGlan Laser prism polarizer is made of two same birefringent material prisms that are assembled with an air space. The polarizer is a modification of the Glan Taylor type and is designed to have less reflection loss at the prism junction. The polarizer with two escape windows allow the rejected beam to escape out of the polarizer, which makes it more desirable for high energy lasers. The surface quality of these faces is relatively poor as compared to that of entrance and exit faces. No scratch dig surface quality specifications are assigned to these faces. The polarized field F1 and F2 of these is shown in the plot below.Angular Field vs Wavelengtha -BBO, 200-300nma -BBO, 300-700nma -BBO, 700-3000nmCalcite, 350-2300nmYVO4, 500-4000nmFeatures:Air-spacedClose to Brewster's Angle CuttingHigh Polarization PurityShort LengthSuitable for low to medium power onring where the rejected beam is not requiredSpecifications:Material:a -BBO, Calcite or YVO4Wavelength Range:a -BBO: 200-3500 nm, Calcite: 350-2300 nm, YVO4: 400-5000 nmExtinction Ratio:Calcite:<5x10 -5 ; a -BBO:<5x10 -6 ; YVO4:<5x10 -6Parallelism:<1 arc MinSurface Quality:20-10Beam Deviation:< 3 arc minutesWavefront Distortion:l/4@633nmDamage Threshold:>500 MW/cm 2Coating:Single layer MgF2Mount:Black Anodized AluminiumStandard Products1.a-BBO Glan Laser PolarizerPart No.  Wavelength Rang(nm)  Extinction RatioAngular Field(°) C.A. fa(mm) O.D. fd(mm) L ±0.1(mm)GLP5206 200-270  <5x10-6 >6.0°GLP5306 300-700 <5x10-6 >6.0°GLP5706  700-3000 <5x10-6  >6.0°2.
