Polarizing beamsplitter cubes for medium energy applications

Polarizing beamsplitter cubes are easy-to-handle, high contrast and high extinction ratio polarizer that splits a randomly polarized beam into two orthogonal, linearly polarized components. Cement is used to bind the two prism halves that form the cube, so the laser damage threshold is limited.


  • Easy, deformation-free mounting
  • High extinction ratio in transmission: Ts/Tp > 200:1
  • No ghost reflections
  • Minimal beam displacement
  • Negligible absorption of reflected and transmitted beams
  • For collimated beams only
  • Input and output surfaces are AR-coated for specified wavelengths
  • Custom sizes are available on request
