355nm 10.0×10.0xH4.6mm PBS Cube(High Power)

P/N: PBSC-355-10-H4.6-HP

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.
