BARRINGTON, N.J., June 7, 2013 — The TechSpec off-axis parabolic mirrors from Edmund Optics are designed for low scatter in the visible spectrum and are suitable for beam expansion, optical testing systems, and focusing or collimation applications. The mirrors are designed to direct and focus incident collimated light at 90º, simplifying system integration. Each device undergoes a visual inspection with a HeNe laser to ensure low scatter. The aluminum substrate mirrors are characterized by improved surface roughness and surface figure as compared to standard off-axis parabolic mirrors. They are available in five models with diameters of either 25.4 or 50.8 mm and with effective focal lengths of 25.4, 50.8 or 101.6 mm.
