About the company
Electro Scientific Industries Inc., operating as ESI and a subsidiary of MKS Inc., sells electrical and electronic measuring instruments, analytical laboratory equipment, and precision equipment repair and maintenance services to federal agencies as a prime contractor (99% of recent awards) and minimally as a subcontractor. ESI is a for-profit manufacturer of goods headquartered in Beaverton, Oregon, with a product and service footprint anchored in NAICS 333517 (Machine Tool Manufacturing) and PSC 6625 (Electrical and Electronic Properties Measuring and Testing Instruments), the latter accounting for 240 of its 304 tracked awards spanning back to 1979.
ESI's customer base is diffuse across the federal government, with 24 distinct agencies served. By award count, the top five customers — the Department of the Air Force (78 awards), the Department of the Navy (57 awards), the Defense Logistics Agency (10 awards), the Department of Health and Human Services Food and Drug Administration (7 awards), and the Department of the Army (7 awards) — account for 52% of awards. By potential value, however, the distribution shifts markedly: HHS Food and Drug Administration carries $221 thousand across 7 awards, the Navy's Office of Naval Research $159 thousand across 4 awards, the National Oceanic and Atmospheric Administration $133 thousand, and NASA Glenn Research Center $96 thousand. This divergence signals that ESI's Air Force and Navy volume consists of small orders, whereas civilian research and development agencies anchor higher potential-value awards. The combined potential value across all awards stands at $1.2 million, but obligated dollars total $19.9 million — a ratio indicating historical work volumes and payment patterns that dwarf the open pipeline.
ESI places task orders under two GSA Federal Supply Schedules (GS00S86287 with 7 task orders and GS00S57230 with 6 task orders) and multiple Air Force indefinite delivery contracts, including DAAB0782CH003 and F3365983C0052. Recent subcontract work includes maintenance, repair, and operation services for the Los Alamos National Laboratory MKS Instruments sub-award under Triad National Security and laser and Glass Grid equipment work under Honeywell Federal Manufacturing & Technologies' National Security Campus contract. Activity remains sparse in the recent record — one award in 2024 and two in 2025 — after decades of consistent volume, suggesting either a transition in how federal work is captured in the source data or a shift in ESI's operational scope under its MKS parent. The parent vendor MKS Inc. also maintains a subsidiary, New Wave Research, Incorporated.
