Lateral Displacement Polarization Beamsplitter, Output Two Parallel
Beams Overview: Lateral Displacement Polarizing Beamsplitters consist of one or
more precision rhomboid prisms cemented to a precision right angle
prism.The lateral displacement polarizing beamsplitters output two
parallel beams separated by a fixed distance. And the displacement
is decided by the size of rhomboid prism. The cemented surface is applied with polarizing beamsplitter
coating(with p-polarization transmission of >95%, s-polarization
reflection of >99% and an extinction ratio of >1000:1) and
entrance and exit faces feature a multi-layer anti-reflection (AR)
coating for increased efficiency. By adding a waveplate can adjust the polarization state of the
output beams. The high-tolerance design prims ensure that the
exiting beams are parallel to within 30 arc seconds. General Specifications of Lateral Displacement Polarization
