Techspec Elliptical Plate Beamsplitters

The Techspec Elliptical Plate Beamsplitters from Edmund Optics maximise beamsplitting efficiency while minimising valuable mounting space. When the beamsplitter is orientated at 45º in the optical path, it creates a circular aperture equal to the diameter of the minor axis. The beamsplitters are available in two thicknesses: 1.0mm for ultra-tight spaces, or 3.0mm with improved surface accuracy. They are available in both the popular VIS and NIR 50/50 beamsplitter coatings and feature a high efficiency multilayer antireflection coating to reduce back reflections.
