Product Family Description

  • Multiple Polarization Materials Available
  • UV to IR Ranges Offered
  • Large Deviation of Ordinary and Extraordinary Rays
  • Rochon Polarizers Also Available

Wollaston Polarizers consist of two birefringent right angle prisms cemented together, such that their optical axes are perpendicular. As light passes through the polarizer, a symmetric deviation between the ordinary and extraordinary beams is created. The resulting beams are of orthogonal linear polarization states and have equal intensity and a large angular deviation. Users have access to both the ordinary and extraordinary rays, making them ideal for laboratory experiments.
