Beamsplitter Plates

A beamsplitter is any optical component that is used to split light into, or recombine from, two separate beam paths. Esco manufactures general purpose beamsplitter plates for use in the visible and UV spectra.


  • Compact, lighter than cubes with similar apertures
  • No epoxy is used, so use with higher power lasers is possible
  • Transmitted and reflected wavefronts are easier to control
  • Beams travel different optical paths
  • R/T radio is dependent on the state of polarization
  • Internal reflection from the second surface produces ghost image in the reflected path
  • Can be built with custom wedge to divert back reflections from beam path
  • Beam can be shifted angularly by controlling the wedge, or laterally by controlling the thickness
