Elliptical Plate Beamsplitters maximize beamsplitting efficiency while minimizing required mounting space. When oriented at 45deg, the beamsplitters create a circular aperture equal to the diameter of the minor axis. Elliptical Plate Beamsplitters are coated with non-polarizing splitting layers and high efficiency multi-layer anti-reflection (AR) coating to reduce back reflections.
