Polarizing beam splitter cube thorlabs.

We have installed it into the optical scheme and discovered some strange behavior. Our plate beamsplitters have a coated front surface that determines the beam splitting ratio while the back surface is wedged and ar coated in order to minimize ghosting and interference effects. Thorlabs offers a wide range of optical beamsplitters. 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. 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. In addition birefringent crystals and brewster windows are also offered for higher laser damage threshold requirements.
