Techspec Elliptical Plate Beamsplitters

Share this on social media:

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.
