Retroreflectors
Staff -- Test & Measurement World, 5/1/2004
Edmund now offers high-tolerance corner cube retroreflectors, designed to return a beam upon itself, regardless of the angle of incidence. These precision retroreflectors provide a 1-arc-second parallelism between the incoming and exiting beams. A silver coating enhances overall efficiency of these prisms by reflecting more light back to the source. Edmund Optics, Barrington, NJ. 856-573-6250; www.edmundoptics.com .
