Edmunds Optics introduced TECHSPEC Elliptical Plate Beamsplitters which are designed to maximize beamsplitting efficiency while minimizing valuable mounting space. When the beamsplitter is orientated at 45° in the optical path, it creates a circular aperture equal to the diameter of the minor axis. The beamsplitters are available in two thicknesses: 1.0 mm for ultra-tight spaces, or 3.0 mm with an improved surface accuracy of 1/4. 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. A complete range of Elliptical Plate Beam Splitters is in-stock and ready to ship at prices from $90. RoHS Certificates of Compliance are available for many models.
