About the company
49Chestnut LLC, doing business as Boston Electronics, supplies advanced electro-optical components and specialized photonics equipment to federal research and development agencies as a prime contractor on full-and-open purchase orders. The Brookline, Massachusetts-based for-profit limited liability partnership operates as a child entity of Fiber Optic Center Inc., a Subchapter S corporation parent. Boston Electronics competes exclusively in unrestricted procurements with no set-aside participation across its 183 total federal awards.
Boston Electronics' capability footprint centers on time-correlated single photon counting (TCSPC) systems, quantum cascade lasers (QCLs) tuned for specific spectroscopic applications (nitric oxide sensing, carbon dioxide measurement in combustion environments), multiphoton microscopy systems with fluorescence lifetime imaging, LIDAR data acquisition platforms, terahertz power sources, and optical detector assemblies. Recent representative work includes a $23,786 purchase order from the Department of Energy's Office of Fossil Energy (awarded September 2026) for a quantum cascade laser system in the mid-infrared region for planar laser-induced fluorescence measurements of CO2, a $78,761 purchase order from the National Institute on Alcohol Abuse and Alcoholism (June 2026) for a portable multiphoton microscope for biosensor detection in living animals, a $243,951 Federal Communications Commission purchase order (September 2022) for terahertz/sub-terahertz power sources supporting 5G/6G propagation testing, and a $75,400 National Institute of Child Health and Human Development purchase order (July 2023) for TCSPC power packages and detector components.
Customer concentration spans research-intensive civilian agencies with modest dollar concentration. The top five customers by award count account for 43 percent of awards: the Office of Naval Research (22 awards, $593 thousand combined potential value), NASA Goddard Space Center (18 awards, $298 thousand), the National Institute of Standards and Technology (16 awards, $533 thousand), the National Institute of Child Health and Human Development (12 awards, $376 thousand), and the National Institute on Alcohol Abuse and Alcoholism (11 awards, $435 thousand). The top five by potential value show similar agencies but different sequencing — ONR and NIST anchor dollars, while NIAAA ($435 thousand) and NICHD ($376 thousand) rank above NASA Langley ($301 thousand) — indicating that Boston Electronics captures volume at ONR and NIST but delivers higher-value equipment orders to NIH institutes. Across 41 distinct customer agencies, Boston Electronics has worked with the National Institutes of Health and its sub-agencies, NASA field centers, the Federal Communications Commission, the Department of Energy, the Department of Commerce, and the Department of Defense.
Boston Electronics operates under two small blanket purchase agreements (BPA 220030181 and BPA 263MD314351), each supporting one task order. The vendor's award portfolio is categorized primarily under NAICS 42343 (Other Electronic Parts and Equipment Merchant Wholesalers, 88 awards) and NAICS 333319 (Analytical Laboratory Instrument Manufacturing, 43 awards), with secondary presence in semiconductor and measuring device manufacturing. Most awards carry the Laboratory Equipment And Supplies PSC (81 awards), with secondary activity in Semiconductor Devices and Optical Instruments PSCs. Activity has averaged 3-5 awards per year over the past five years, with two awards in 2026 and three in 2025. The recompete cliff in the next twenty-four months includes two awards with combined potential value of $103 thousand. Boston Electronics subcontracts minimally — a single sub-award to The Aerospace Corporation (August 2023) for engineering services on distributed feedback (DFB) lasers with high heat load housing — indicating a predominantly direct-to-customer prime footprint.
