High-Power Laser-Line Polarizing Beamsplitter Cube PBS25HP-532
JCOPTIX high-power laser-line polarizing beamsplitter cubes comprise two precision right-angle prisms, with a wavelength-specific coating on one hypotenuse. Incident light splits into orthogonal linear polarizations: p transmits and s reflects. The prisms are joined by epoxy-free optical contact bonding rather than ordinary cementing, minimizing absorption and scattering and increasing laser damage threshold. Highly flat, polished surfaces minimize wavefront distortion, while V-type dielectric coatings reduce surface reflection. Wavelength options include 266 nm, 405 nm, 780 nm, 808 nm, 830 nm, 850 nm, 1030 nm, 1550 nm, and major Nd:YAG harmonics at 355 nm, 532 nm, and 1064 nm. Versions premounted in 30 mm cage cube mounts are also available. Contact technical support for other wavelengths or sizes.
