We bought polarizing beamsplitter cube pbs054 at thorlabs 18 sep 2013 web order acknowledgement web n6w421935. Pellicle beamsplitters provide excellent wavefront transmission properties while eliminating beam offset and ghosting. Thorlabs offers both plate and cube polarizing beamsplitters for a variety of wavelength ranges and power handling requirements. Thorlabs offers a wide range of optical beamsplitters.

Thorlabs offers non polarizing cube beamsplitters for visible 400 700 nm nir 700 1100 nm and ir 1100 1600 nm light. Beamsplitter cubes are available with split ratios of 30 70 50 50 or 70 30 and in sizes of 5 mm 10 mm 20 mm and 25 4 mm. We have installed it into the optical scheme and discovered some strange behavior. In addition birefringent crystals and brewster windows are also offered for higher laser damage threshold requirements.
