Polarisers

  • Glan Laser Prisms work well in high performance, high power applications.
  • Glan Taylor and Glan Thompson Prisms provide high extinction ratios.
  • Beamsplitting Thompson Prisms split the s- and p- components.
  • Beam displacers shift the s- and p- components.
  • Wollaston Prisms diverge the s- and p- components.
  • Dichroic polarisers are cost effective and convenient.
  • Quartz waveplates provide controlled retardation.
  • Quartz depolarisers scramble the incoming beam polarisation.
  • Mica waveplates provide controlled retardation over a broadband region.
  • Mid-IR polarisers have similar performance to Glan laser, but are water band absorption free. These polarisers withstand higher powers and allow you to detect in the water band range.
  • Various birefringent materials are used in optical polarisation devices. Calcite polarisers from Laser 2000 are made with a very high grade of optical quality natural calcite crystals, which exhibit only very slight internal striae.
