PHOTON SPOT INC

Photon Spot Inc. specializes in the design, manufacturing, and maintenance of high-precision analytical laboratory instruments, with deep expertise in superconducting nanowire single-photon detectors (SNSPDs) and cryogenic systems. The company develops and supports advanced photon detection platforms operating at cryogenic temperatures, including traveling cryostats, SRI cryostats, and time-resolved emission microscopy systems. Their technical proficiency spans low-temperature physics, superconducting materials engineering, and ultra-sensitive optical detection systems, enabling applications in quantum sensing, photon counting, and high-resolution spectroscopy. Photon Spot’s differentiation lies in its ability to deliver mission-critical instrumentation with exceptional thermal stability, low dark count rates, and metrology-grade reliability—key for federal research and defense applications requiring single-photon-level sensitivity. The contractor maintains a strong, recurring relationship with the Department of Commerce, delivering specialized cryogenic and photon detection systems for scientific metrology and standards development. Additional engagements with the Department of Defense and NASA indicate alignment with national security and space-based sensing missions requiring ultra-low-noise detection technologies. These partnerships suggest a pattern of trusted, repeat procurement for high-reliability, niche instrumentation rather than broad-scale procurement. Photon Spot operates primarily under NAICS 334516, focusing on analytical laboratory instrument manufacturing for scientific and defense applications. Their vertical specialization is in quantum photonics and cryogenic instrumentation, positioning them as a niche supplier for advanced optical sensing systems used in national laboratories, defense R&D, and space instrumentation programs. Photon Spot Inc. is a small business structured as a 2L entity, headquartered in Monrovia, California. While currently holding no formal government certifications, its consistent delivery of technically complex systems to federal agencies demonstrates a proven track record in meeting stringent performance requirements for mission-critical instrumentation.
