TECHSPEC® Elliptical Plate Beamsplitters maximize
beamsplitting efficiency while minimizing required
mounting space. When oriented at 45°, the
beamsplitters create a circular aperture equal to the
diameter of the minor axis. TECHSPEC® Elliptical
Plate Beamsplitters are available with either a visible
or NIR 50% reflection/50% transmission beamsplitter
coating, and feature a high efficiency multi-layer antireflection
(AR) coating to reduce back reflections.
