Polarizing optical beam-splitter
CVI Melles Griot
* Projection systems, signal monitoring, color separation and recombination, optical coupling
* Fewer ghost images than plate beamsplitters
* Optical isolation (in combination with waveplate)
* Continuously variable beamsplitter (In combination with waveplate)
* 1000:1 extinction ratio
Polarizing beamsplitter cubes are used to split a laser beam into two orthogonally polarized components; p-polarization is transmitted straight through while s-polarization is reflected at 90°. PBS polarizer cubes utilize a durable all-dielectric coating at the internal cemented interface, and all external surfaces are antireflection coated for the wavelength specified. For best spectral performance and transmitted wavefront, cube beamsplitters should be used with collimated or near-collimated input light. The PBS and other cemented beamsplitter cubes are easy to mount, mechanically durable and ideal for use up to 1 J/cm2 at 1064 nm.
