AOS optics are deployed around the world in aerospace imaging systems, industrial scanners, research facilities using advanced lasers, and remote sensing applications.

Flemming Tinker is a deep-tech founder and optics manufacturing executive with more than three decades of experience building and scaling advanced optical systems for high-energy laser, aerospace, and space-based applications. He is the Founder and CEO of Aperture Optical Sciences, a specialty manufacturer pioneering scalable silicon carbide optics for demanding commercial and government markets.
Trained in optics at the University of Rochester and manufacturing engineering at Boston University, Mr. Tinker advanced through technical and operational leadership roles at Zygo Corporation, where he led programs supporting semiconductor lithography, space systems, and large-aperture laser facilities, including the National Ignition Facility.
Under his leadership, AOS has delivered 20,000+ silicon carbide mirrors, developed two dozen satellite telescopes currently on orbit, and generated nearly $60M in cumulative revenue, with deployments in 14+ countries.

Dan received his B.S. in Engineering Physics from the University of Nebraska and his M.S. in Physics from the Georgia Institute of Technology.
He began his career with Perkin-Elmer in Wilton, Connecticut, where he supported the production of precision optics for the semiconductor industry. After approximately three years, he transferred to the company’s Danbury facility and joined the metrology department. During the fabrication of mirrors for NASA’s Chandra X-ray Observatory, Dan became deeply involved in optical fabrication—an area that has defined his career ever since.
He later led the ALOS PRISM program for Japan Aerospace Exploration Agency (JAXA), serving as program lead for this high-profile international space mission. Dan subsequently spent four years with Zygo Corporation, where he served as Program Manager overseeing semiconductor optics programs for both domestic and international customers.
In 2004, Dan returned to United Technologies (now part of RTX Corporation) in Danbury, contributing technically to the fabrication of advanced optical systems supporting national defense applications.
Dan joined Aperture Optical Sciences (AOS) in 2019 as Vice President and Technical Director. In this role, he leads the company’s technical development strategy, guiding innovation, manufacturing excellence, and long-term technology roadmap initiatives across space and fusion energy optical systems.
Contact DanOur customers are researchers, product developers & technologists. We add value by providing rare expertise in robotic optical fabrication, design for manufacturability and assembly, and verifying product performance using optical metrology.
We are an independent US-owned corporation located in Central Connecticut with partners in Europe and Asia. The name comes from the term “Aperture”, an opening enabling the passage of light, and symbolizes what we provide our customers and employees–a pathway for new ideas and creative solutions using light.
