1064nm 12.7×12.7×12.7mm PBS Cube

P/N: PBSC-1064-12.7

Polarizing beam splitter 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-deg.
PBS Cube is commonly made by precisely cementing two triangular optical prisms together at their hyoptenuse using polyester, epoxy, or urethane-based adhesives.
PHOTONIK polarizing beam splitter cubes utilize a durable all-dielectric optical coating at the internal cemented interface, (Dichroic mirrored prism assembly); 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.

These polarizing beamsplitter cubes use a coating rather than birefringent materials to split S & P polarization with a 90-Deg deviation at 1064nm.
