UNSPSC 41115339: Ellipsometer

Equipment that analyzes the structure of the thin film by measuring the thin film thickness, refraction rate, extinction coefficient, and density with the change shown when reflecting the laser or polarized light on the sample.

UNSPSC 41115339 Ellipsometer is a Commodity code that in recent state and local procurement activity does not correspond to the purchase of ellipsometers or related optical measurement equipment. The two recent opportunities tagged with this code describe Energy Savings Performance Contracting services and Owner's Representative services for facility infrastructure upgrades, neither of which involve ellipsometry or optical instrumentation. This represents a classification mismatch between the code's nominal scope and actual procurement activity, indicating that the code carries little actionable signal for vendors supplying ellipsometers or related metrology equipment to state and local buyers.

The Georgia World Congress Center Authority and the City of Winder, Georgia, are the two issuing bodies posting under this code in recent months. The Authority's RFQ for Owner's Representative services on the GESPC II Project closed June 15, 2026, and seeks qualified firms to manage day-to-day oversight and coordination of large-scale building automation, HVAC, and mechanical system upgrades at the convention center through June 2028. The City of Winder's RFQ for Energy Savings Performance Contracting services, posted February 24, 2026, with responses due March 10, 2026, targets qualified ESCOs to conduct energy audits, design and install efficiency improvements, and guarantee minimum annual savings across six municipal facilities totaling 115,840 square feet. Both opportunities are confined to Georgia and reflect energy infrastructure modernization activity rather than laboratory or measurement-equipment procurement, suggesting the code assignment is erroneous rather than indicative of a viable market segment for ellipsometer sales.
