TechSpec Beamsplitters

For Space-Constrained Applications
BARRINGTON, N.J., Aug. 15, 2007 -- TechSpec elliptical plate beamsplitters are designed to maximize beamsplitting efficiency while minimizing valuable mounting space, said the product's maker, Edmund Optics Inc.

When the beamsplitter is orientated at 45º in the optical EOTechSpec.jpgpath, it creates a circular aperture equal to the diameter of the minor axis. The beamsplitters are available in two thicknesses: 1 mm for ultratight spaces, or 3 mm with an improved surface accuracy of 1/4. They are available in both visible and near-infrared 50/50 beamsplitter coatings and feature a high efficiency multilayer antireflection coating to reduce back reflections.

"Our elliptical plate beamsplitters have been used in a number of space-constrained applications. 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," said Gregg Fales, Edmund Optics product line manager.

A complete range of elliptical plate beamsplitters is in-stock and ready to ship at prices from $90, the company said. RoHS compliance certificates are available for many models.

An optical device for dividing a beam into two or more separate beams. A simple beamsplitter may be a very thin sheet of glass inserted in the beam at an angle to divert a portion of the beam in a different direction. A more sophisticated type consists of two right-angle prisms cemented together at their hypotenuse faces. The cemented face of one prism is coated, before cementing, with a metallic or dielectric layer having the desired reflecting properties, both in the percentage of reflection...
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
