Wedge Prism Pairs
Jan 2012Research Electro-Optics Inc. (REO)Request Info
REO is offering a family of matched Risley (wedge) prism pairs to enable high-accuracy laser beam steering in military, industrial and instrumentation applications. Beam steering accuracy with the coated optics is dependent upon close matching of the prisms in a pair. The company matches prism pair wedge angles to <0.5 arcsec and bulk material indices of refraction, and controls internal coating layer stresses to guarantee that the deposition process does not degrade the transmitted wavefront performance, which is specified at <λ/10 at 632.8 nm. The Risley prism pairs also feature low scatter, low-loss surfaces with 10-5 scratch-dig surface quality to maximize throughput and laser damage threshold.
