BARRINGTON, N.J., 17 Aug. 2007.Edmund Optics Inc. in Barrington, N.J., is offering the TECHSPEC elliptical plate beamsplitters to make the most of beamsplitting efficiency while minimizing mounting space.
When the beamsplitter is oriented at 45 degrees 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 the VIS and NIR 50/50 beamsplitter coatings and feature a multilayer antireflection coating to reduce back reflections.
"Our elliptical plate beamsplitters have been used in a number of space-constrained applications," says Gregg Fales, Edmund Optics product line manager. "They provide 40 percent more clear aperture than would a circular beamsplitter using the same amount of physical space, which has helped us design some compact, highly efficient illumination assemblies."
