Our Lateral Displacement Beamsplitters output two parallel beams separated by 10 or 20mm, depending on size chosen. Beamsplitters consist of a precision rhomboid prism cemented to a 1/8 wave right angle prism. The high tolerance design ensures the exiting beams are parallel to within 30 arc seconds. Entrance and exit faces feature a multi-layer AR coating for increased efficiency. Polarizing and non-polarizing options are available. Non-Polarizing are available with visible or near-IR coating options.
