PSM mounting hardware
Customers purchasing a PSM often ask me if we offer mounting hardware for the PSM like x-y-z stages.
My answer has been “No”, because there are so many ways of using the PSM that it would be impossible to meet everyone’s different needs.
In fact, the answer is “Yes!”
The centering station is a tall, motorized and encoded z stage with x-y lateral adjustments more than adequate to keep an image within the PSM field of view.
I use the centering station daily because it is so convenient.
Rather than attaching the PSM to an x-y-z mount as a first step, I simply move the lens or assembly to the centering station and I am ready for almost any type of lens measurement.
For any sort of measurement you might do on a classical optical bench, the centering station is a convenient and cost effective solution.
And being vertical, gravity is your friend.

Robert Parks
Robert Parks received a BA and MA in physics from Ohio Wesleyan University and Williams College, respectively. His career started at Eastman Kodak Company as an optical engineer and then went on to Itek Corp. as an optical test engineer.
He learned about optical fabrication during a 4 year stay at Frank Cooke, Inc. This experience led to a position as manager of the optics shop at the College of Optical Sciences at the Univ. of Arizona and where he worked for 12 years and had a title of Assistant Research Professor. During that time he had the opportunity to write about the projects in the shop and the optical fabrication and testing techniques used there including papers about absolute testing and the installation and used of a 5 m swing precision optical generator.
Mr. Parks left the University in 1989 to start a consulting business specializing in optical fabrication and testing. Among the consulting projects was one working for the Allen Board of Investigation for the Hubble Telescope where he stayed in residence at HDOS for the duration of the investigation. In 1992 he formed Optical Perspectives Group, LLC as a partnership with Bill Kuhn, then a PhD student at Optical Sciences.
The consulting and experience with Optical Perspectives provided many more opportunities to publish work on optical test methods and applications. While still at Optical Sciences, Mr. Parks became involved in standards work and for twenty years was one of the US representatives to the ISO Technical Committee 172 on Optics and Optical Instruments. For two years he was the Chairman of the ISO Subcommittee 1 for Fundamental Optical standards. Recently Mr. Parks temporarily rejoined Optical Sciences part time helping support optical fabrication projects and teaching as part of the Opto-Mechanics program.
Bob is a member of the Optical Society of America, a Fellow and past Board member of SPIE and a member and past President of the American Society for Precision Engineering. He is author or co-author of well over 100 papers and articles about optical fabrication and testing, and co-inventor on 6 US patents. He remains active in development of new methods of optical testing and alignment.
