Beamsplitter
The beamsplitters described here are mainly for CO₂ laser systems at 10.6µm and 45° incidence, since their thin-film coatings have stringent wavelength and angle requirements. When these conditions are met, the beamsplitter transmits a specified fraction of incident optical energy and reflects the remainder. Ordinary beamsplitters split or combine laser beams; polarizing beamsplitters split or combine beams with two orthogonal polarization states. Performance is mainly determined by the coating characteristics.

Cemented PBS Prism PBS2005
Beam Splitters
U-photonics
Material: K9 or ZF Glass; Fused Silica Wavelength Range: 350~2300nm Dimensional Tolerance: +/-0.1mm
A polarizing beamsplitter cube separates unpolarized input into orthogonal linear polarizations: P transmits fully and S reflects at 45°, exiting at 90° to P. Two precision UV-fused-silica right-angle prisms are bonded, with a dielectric polarizing coating on one hypotenuse. Any surrounding face can be an entrance, but best polarization performance uses the perpendicular face of the coated prism; a black dot on top identifies it. Laser-line cubes offer Tp:Ts>3000:1. Four transmitting faces have single-wavelength V-type AR coatings with reflection <0.25% at the design wavelength. Ten options are 405, 532, 633, 780, 808, 830, 850, 1030, 1064 and 1550nm.
