Lateral Displacement Beamsplitters

Visible and NIR Coating Options Offered
Simplifies Benchtop Layout
Split Incident Beam into Two Displaced Parallel Beams

TECHSPEC® Lateral Displacement Beamsplitters output two parallel beams separated by a fixed distance. The beamsplitters consist of a precision rhomboid prism cemented to a 1/8λ right angle prism. The high tolerance design ensures the exiting beams are parallel to within 30arcseconds. Entrance and exit faces feature a multi-layer anti-reflection (AR) coating for increased efficiency. Polarizing and non-polarizing coatings are available.
