  • Flemming Tinker

    President & Founder

    Flemming Tinker has been working in the field of optics engineering and manufacturing for over 30 years and holds degrees in Optics from the University of Rochester, and Manufacturing Engineering from Boston University. Mr. Tinker is a specialist in optics manufacturing & management involving innovative technologies.

    Before founding Aperture Optical Sciences, Inc., Mr. Tinker worked as Senior Engineer, Director of Manufacturing, and Director of the Optics Business Unit for Zygo Corporation and Operated an Engineering and Consulting Firm serving clients in the Optics Industry.

    Mr. Tinker has lead development efforts in high laser damage resistant thin film coating and optics manufacturing, lightweight space based telescope optics for satellite communications, optics for aerospace recon, and developed automated techniques for meter scale laser optics production. Mr. Tinker was one of the key developers of the technology for producing nearly 7,000 meter size laser optics for Lawrence Livermore National Laboratory’s National Ignition Facility (NIF). Mr. Tinker holds patents in interferometry and optical components for lithography.

    After founding AOS with Kai Xin in 2010, Mr. Tinker has assembled a talented team of professionals and dedicated employees to build AOS into an innovation engine for 21st century optics manufacturing.

  • Kai Xin, PhD

    Chief Technical Officer

    Dr. Xin is responsible for leading all efforts in technology, software, and product and process development for Aperture Optical Sciences Inc. Dr. Xin is an expert in Aspheric Optics metrology and fabrication. Dr. Xin holds a PhD in Mechanical Engineering from the University of Rochester. Working with his advisor, Professor John C. Lambropoulos, Dr. Xin developed unique research and analysis of sub-surface damage related to optics processing. After completing his Thesis, Dr. Xin worked for Zygo during 2003 to 2006 to develop, design and implement the manufacturing process and equipment for high-energy laser optics for Lawrence Livermore’s National Ignition Facility. Combining his unique knowledge in process science, materials, equipment design, and software/algorithm development, Dr. Xin developed a mass production system combining generating, fixed abrasive lapping, multi-stage pad polishing, computer controlled polishing, and MagnetoRheological Finishing (MRF) for laser optics. Following this process, the National Ignition Facility reported the highest achieved laser damage threshold for this material type.

    Dr. Xin originated a concept of a flexible development/production system to successfully eliminate the risk and maximize process predictability in optics manufacturing. This was critical to defining and implementing a production system for state-of-the-art optics like high damage threshold components.

    Dr. Xin has over 20 years experience in areas related to process development, equipment design, instrument design, control system design, simulation, algorithm development, optical metrology, and software design.
