UNSPSC 41115306: Interferometers

UNSPSC 41115306 Interferometers is a Commodity code representing specialized optical instrumentation equipment purchased by state and local government entities, including research universities, for laboratory and scientific applications. The recent procurement record shows minimal alignment between the code's nominal scope and actual solicitation activity. Of the five state and local opportunities tagged to this code, only one directly addresses interferometers: the University of Wisconsin-Madison's March 2026 RFB for a Field Widened Michelson Interferometer. The remaining four opportunities—ophthalmic instruments from the County of Santa Clara, research and development goods and services from Texas Tech University, career technical education resources from Klein ISD, and a public health lab information management system from the County of Santa Clara—fall outside the interferometer scope and appear to represent taxonomy misclassification rather than legitimate market activity under this code.

The one representative opportunity of direct relevance is University of Wisconsin-Madison RFB 2026-UWMSN-01298-RFB, issued March 17, 2026, with a bid deadline of March 25, 2026, seeking bids for a Field Widened Michelson Interferometer through the ShopUW+ procurement portal. No award value, budget range, or contract term is disclosed in the posted materials. The code shows limited recent state and local procurement activity tied specifically to interferometer equipment; the geographic footprint is restricted to Wisconsin based on available records. Prospective vendors should verify classification accuracy before pursuing opportunities tagged to this code, as the mismatch between the interferometer commodity definition and the broader research-services and specialized-equipment solicitations in the current pipeline suggests either coding inconsistency or a code ill-suited to capture the actual instruments and services state and local buyers are requesting.
