Optical Perspectives Group, LLC (OPG) is a privately held company based in Tucson, Arizona, United States, that develops and supplies instruments for optical alignment, centering, and metrology of optical components and systems.[1]
History
[edit]Optical Perspectives Group was co-founded in 1992 by physicists Robert E. Parks and William Kuhn.[2] The company was established to provide optical design, assembly, and testing expertise for precision optical systems. Since 2005, OPG has been solely owned and operated by Robert E. Parks.[3]
Parks, who holds degrees in physics from the University of Rochester, previously worked in optical fabrication and testing, including consulting on metrology issues related to the Hubble Space Telescope mirror.[4] He has authored or co-authored more than one hundred technical publications and several patents in optical testing and align

Products and technology
[edit]Optical Perspectives Group develops a number of precision instruments used for optical alignment and surface-finish characterization. Among its principal products are:
- The Point Source Microscope (PSM), a portable instrument derived from the autostigmatic microscope concept, used for locating centers of curvature and aligning optical elements and systems.[7]
- The CaliBall (I and II), precision calibration spheres used to characterize interferometer transmission spheres.
- The Micro-Finish Topographer (MFT), used to quantify surface roughness of optical surfaces.[1]
The company has also demonstrated methods using Bessel and Bessel–Gauss beams as alignment references, showing that such beams propagate through optical systems analogously to single rays in design software.[5]
Research and publications
[edit]OPG and its founder have contributed extensively to the optical metrology literature. Published work includes *“Optical alignment using the Point Source Microscope”* (SPIE Vol. 5877, 2005) and *“Optical Alignment Using Bessel–Gauss Beams”*, among others.[5] OPG’s research and white papers are available through its company website and have been cited in trade publications and scientific databases such as Bioz.com and AZoOptics.[8]
Markets and applications
[edit]OPG’s customers include research laboratories, aerospace and defense contractors, and optical manufacturing companies. Its products are used internationally for aligning lenses, mirrors, and interferometer systems where sub-micrometer and sub-arc-second accuracy is required.[9]
External recognition
[edit]The company is listed in the corporate-member directory of the International Society for Optics and Photonics (SPIE).[1]
