The Techspec elliptical plate beamsplitters from Edmund Optics Inc. are designed to provide beamsplitting efficiency in applications where space is limited. The company says the devices provide 40 percent more clear aperture than would circular beamsplitters using the same amount of space, enabling the design of compact illumination assemblies. When the beamsplitters are oriented at 45° in the optical path, they create a circular aperture equal to the diameter of the minor axis. They are available in VIS and NIR 50/50 coatings and in thicknesses of 1.0 mm for ultratight spaces or 3.0 mm with a surface accuracy of λ/4. Their multilayer antireflection coating reduces backreflections.
