Polarizing beamspiltter cubes

Polarizing beamsplitter cubes offer several advantages over plate beamsplitters. They are easy to handle, high contrast and high-extinction-ratio polarizers that split a randomly polarized beam into two orthogonal, linearly polarized components.

These products are typically used in laser-beam separation and combination, and optical-isolation applications. The epoxy-free construction of the cubes enables superior performance at high energy levels.


  • Easy, deformation-free mounting
  • High extinction ratio in transmission: Tp/Ts > 1000:1
  • Low-reflected and transmitted wavefront distortion
  • No ghost reflections
  • Minimal beam displacement
  • Negligible absorption of reflected and transmitted beams
  • High transmission of p-polarization: Tp > 97%
  • For collimated beams only
  • Input and output surfaces are AR-coated for specified wavelengths
  • Custom sizes are available on request
