Lateral Displacement Polarization Beamsplitter
          
           Lateral displacement polarization Beamsplitter produces two parallel output beams which are separated by a lateral displacement. And the displacement is depended on the size 
of rhomboid prism. This Beamsplitter consists one or two rhomboid prisms cemented to a right angle prism, and in some particular applications, we can add a waveplate to adjust 
the polarization of the output beams. The parallelism between input and output beams can be realized within 30 arc seconds. All entrances are coated with multi layer anti-reflection 
coating.
