Thomas Keating LIMITED

Thomas Keating LIMITED, a United Kingdom-based manufacturer of precision optical and instrumentation components, supplies specialized parts and assemblies to federal research institutions as a prime contractor on a full-and-open basis, with no use of set-asides across its footprint. The company is a for-profit corporate entity headquartered in Billingshurst, West Sussex, and manufactures optical instruments, waveguide components, cryogenic detector assemblies, and laboratory instrumentation under primary NAICS 334613 (Optical Instrument and Lens Manufacturing) and related manufacturing classifications. All 34 awards in the source data are prime contracts; the vendor operates with no subcontract exposure.

Thomas Keating's customer base concentrates heavily with federal research institutions. The Smithsonian Institution accounts for 14 awards (82% share by count, 36% by combined potential value of $396 thousand) and anchors the relationship through recurring purchase orders for WSMA (Waveguide Submillimeter-wave Mixer Array) receiver components, mixer blocks for cryostats, and optical cartridge parts supporting submillimeter astronomy instrumentation. The National Institute of Standards and Technology ($248 thousand across 2 awards), NASA Shared Services Center ($179 thousand across 4 awards), the National Institute of Diabetes and Digestive and Kidney Diseases ($103 thousand across 4 awards), and the Office of Naval Research ($47 thousand across 4 awards) round out the top five customer agencies. The top-five customer concentration stands at 88% of combined potential value, with Smithsonian and NIST together representing over half of all dollars.

Recent awards include a $38 thousand September 2026 purchase order from the Smithsonian for optical parts (due December 17, 2026), a $29.2 thousand March 2026 order for WSMA receiver components, a $62 thousand February 2023 order for waveguide cartridge optics, and a $54 thousand May 2023 order for mixer blocks. Activity has remained sparse and episodic — two awards in 2019, four in 2020, and only two in each of 2021, 2023, and 2026 to date. One award ($38 thousand) reaches completion within the next twenty-four months. The combined obligated value across all 34 awards equals the combined potential value at $1.1 million, indicating full funding or cash close on the entire footprint.
