About the company
Photon Spot Inc., a minority-owned, Subchapter S corporation based in Monrovia, California, manufactures advanced cryogenic systems and superconducting nanowire single photon detectors for federal research agencies as a prime contractor across full-and-open and small-business-set-aside procurements. The company operates entirely as a prime (100% of recent awards) with no subcontract footprint, competing in open market and total small business set-asides without 8(a) certification.
Photon Spot's capability portfolio centers on 4K cryogen-free cryostats, Standard Reference Instrument (SRI) cryostats, single-photon detection systems optimized for quantum science and metrology research, time-resolved emission microscopy systems, and maintenance and repair services on installed cryogenic equipment. Representative recent work includes a $412,600 firm-fixed-price purchase order from the National Institute of Standards and Technology (NIST) for time-resolved emission microscopy cryostats (awarded September 2024), a $158,774 delivery order under Photon Spot's single-award Indefinite Delivery Contract with NIST for a Standard Reference Instrument cryostat (awarded August 2026), a $220,469 total-small-business purchase order from NIST for a 4K cryogen-free cryostat system (awarded September 2026), a $52,396 sole-source purchase order from the Air Force Research Laboratory for superconducting nanowire single-photon detectors (awarded May 2025), and a $283,394 Cooperative Agreement under NIST's CHIPS Research and Development program (CFDA 11.042) to develop an ultra-compact, ultra-low vibration cryogenic system for time-resolved imaging and deep-space optical communications (awarded October 2024 with performance through July 2027).
Customer concentration is pronounced. NIST accounts for 25 awards and $6.2 million in combined potential value (95% of award count and 66% of dollars), with the Defense Advanced Research Projects Agency, the Army's Materiel Command Research Development and Engineering Command, and the Air Force Research Laboratory rounding out the active customer base. The company holds a single-award Indefinite Delivery Contract with NIST valued at $2.4 million ceiling with performance through March 2027, against which five task orders have been placed. Activity accelerated from one award per year in 2022–2023 to seven in 2024, stabilizing at five awards in 2025 and three in 2026. Only two awards (combined potential value $379 thousand) face ultimate completion within the next twenty-four months, reducing near-term recompete exposure. Photon Spot's work is performed entirely in Monrovia, California. The vendor qualifies as a minority-owned small business but does not carry 8(a) or HUBZone designation and competes predominantly in open solicitations and total small business set-asides.
