UNSPSC 31241800: Optical filters

UNSPSC 31241800 Optical filters (Class) comprises microscopes, optical lenses, frames, and related accessories that state and local governments buy for educational laboratories, scientific facilities, and institutional research functions. Recent solicitations show that optical inspection and magnification equipment — including multiple microscope types, supplementary accessories, and lens assemblies — drive activity under this code. Issuing bodies include state purchasing offices coordinating cooperative agreements and individual state agencies. The Texas Comptroller of Public Accounts and the State of Michigan are recent active buyers, with Texas operating a cooperative purchasing vehicle (TCPN) that aggregates demand across multiple state and local agencies to consolidate volume and negotiate firm fixed-price unit costs for microscope equipment and accessories.

Texas and Michigan account for the most recent solicitation activity under the code. The Texas Comptroller's cooperative purchasing requisition 304T27490M2, posted August 5, 2026 with a response due September 1, 2026, solicits proposals for microscopes and accessories under an indefinite-quantity, requirements-type agreement with a 120-day response window following the due date; respondents must provide mandatory certifications, insurance statements, and firm fixed-price unit cost pricing sheets for specified microscope products and related equipment, with warranty provisions covering defects and repairs. Michigan's Notice of Intent for RFP 250000002612, posted July 27, 2026 with a deadline of July 31, 2026, concerns optical lenses and frames, though the underlying RFP scope, estimated value, and detailed evaluation criteria are not fully disclosed in available summary documents.
