Rayleigh Optical Corporation is a small company founded by David and Vilma Anderson. As with many entrepreneurs, the company started out from the garage of our home in 1987. Today ROC enjoys 10,000 square feet of space dedicated to the manufacturing of optics.
Through the years we have manufactured optics for many astronomy institutions, and we have enjoyed working with some very knowledgeable and creative astronomers and engineers.
We specialize in making large aspherical optics. Our testing capability and manufacturing experience sets as apart from other small shops.Our optics can be found worldwide at major astronomical sites, in national laboratories, and in the workplaces of large corporations.
Director of Optics
David Anderson is in charge of the manufacturing of Optics. His career in optics started in 1977 at the Optical Sciences center at the University of Arizona. His responsibilities were in the areas of fabrication and testing of a wide variety of optics. One of his projects included the MMT #7 mirror where he performed the first known direct phase-measurement of a large telescope mirror.
In 1989 he became the head optician at the Steward Observatory Mirror Lab when it first opened. He worked on several large mirrors including the 3.5-m SOR primary, the 3.5-m ARC primary, the 3.5-m WIYN primary and the 1.8-m/f1 primary for the Vatican Advanced Technology Telescope (VATT). His final project at SOML was working the initial stages of the 6.5m MMT telescope primary from which he left to devote his full time to ROC.
He also worked at Perkin-Elmer in Connecticut where he was the lead engineer in the development of a spherical continuous polisher to fabricate very fast spherical mirrors for microlithography. He also worked on developing methods of polishing Germanium on CP machines.
At Spectra-Physics in California, he worked in the R&D group responsible for implementing into production the first commercial phase-measuring interferometer called DIAD as well as the operation of two large CP machines making high precision laser optics. He also developed the generating process that lead to the elimination of loose-abrasive grinding of plano substrates.
David is an author of numerous papers on optical fabrication and holds a patent for the testing of convex aspherics using a holographic test plate.
President & CEO
Vilma E. Londono-Anderson is the President and co-founder of the company.She has a bachelor’s degree in Chemical Engineering and an MBA. Her engineering experience started with Xerox Corporation where she was a process engineer in the manufacturing area of photoreceptors. Her Xerox experienced involved Thin Film Vacuum Technology and Process Control. Later she transferred to the Sales and Marketing division where she successfully completed all the sales training programs and gained experience in business operations.
Mrs. Anderson also worked as a manufacturing engineer for Burr-Brown Corporation, a worldwide producer of microelectronics, now owned by Hewlett Packard. She was the project/process engineer in the manufacturing facilities in the areas of wafer cutting and die attach.
As the co-owner and co-founder of Rayleigh Optical, Vilma has wide experience in all facets of the business of optical fabrication, an experience that augments her ability to work well with customers, suppliers and vendors.
