About Photon Spot Inc.
Photon Spot Inc., a minority-owned, for-profit Subchapter S corporation headquartered in Monrovia, California, manufactures advanced cryogenic systems and superconducting nanowire single photon detectors (SNSPDs) for federal research agencies, operating exclusively as a prime contractor across full-and-open and total small business set-aside vehicles. The company competes in NAICS 334516 (Analytical Laboratory Instrument Manufacturing) and primary PSC Laboratory Equipment and Supplies, with a customer concentration heavily anchored to the National Institute of Standards and Technology.
Photon Spot's customer footprint is concentrated and singular. NIST accounts for 23 of 33 awards captured in recent activity (94% of award count by the top-four customer ranking), with $5.8 million in combined potential value — vastly outweighing secondary customers. The Defense Advanced Research Projects Agency holds two awards valued at $1.6 million; the Army's Materiel Command Research Development and Engineering Command, four awards at $664 thousand; and the Air Force Research Laboratory, three awards at $534 thousand. Across the top five customers, concentration reaches 99% of combined potential value. This deep NIST dependency reflects Photon Spot's specialization: the agency procures from the vendor's core product line of cryogenic metrology equipment for quantum science research.
Photon Spot operates under a single-award Indefinite Delivery Contract with NIST (IDC 1333ND24DNB670001, ceiling $2.4 million, performance through March 2027) that has generated four delivery orders valued between $144,026 and $299,574 each. Representative prime work includes a $570,636 total small business set-aside purchase order from NIST (September 2021) for a cryostat prototype with 250 megawatts of cooling power below 4.5 Kelvin and temperature stability under 20 milliKelvin; a $412,600 full-and-open purchase order from NIST (September 2024) for time-resolved emission microscopy cryostats supporting metrology research; a $283,394 Cooperative Agreement under the NIST CHIPS Research and Development program (CFDA 11.042, October 2024 to July 2027) to develop an ultra-compact, ultra-low vibration cryogenic system for time-resolved imaging applications, with planned sub-awards for deep space optical communication testing; and multiple delivery orders under the IDC for Standard Reference Instrument (SRI) cryostats and 4K cryogen-free systems. AFRL work includes a $101,204 photon spot detector purchase order (April 2023) and a $52,396 SNSPD order with detector electronics and cryostat components (May 2025) marked as sole-source justified by prior custom software integration.
Activity has accelerated recently — one award annually in 2022 and 2023, growing to seven in 2024 and five in 2025 — but the recompete exposure is minimal: only one award ($150 thousand) completes within the next twenty-four months. Combined potential value across all 35 prime awards stands at $9.1 million, with $6.7 million (73%) obligated. The vendor operates with no subcontract footprint and no federal grant sub-recipient activity — all 35 awards are prime direct performance. Photon Spot's only named vehicle is the NIST IDC; the company does not appear on government-wide vehicles such as GWACs or Schedule contracts, limiting visibility and teaming leverage outside the metrology and quantum science community.
