UNSPSC 41111741: Microscope differential interference contrast equipment

Equipment that uses the interference effect of light to display the object shown on plane to show the sense of dimension with the height by installing the prism corresponding to each multi-ratio of the objective lens on the condenser.

UNSPSC 41111741 Microscope differential interference contrast equipment is a Commodity code under which state and local governments procure professional-grade comparison microscopes and FTIR (Fourier-transform infrared) microscopy systems for forensic analysis, laboratory research, and educational applications. Recent solicitations show demand for dual-unit comparison microscopes with split-field capability, magnification ranges of 4x to 40x, 4K resolution imaging, motorized stages accommodating fired ammunition and forensic samples, and associated accessories including objective lenses, eyepieces, and software. Issuing bodies include state law enforcement agencies (Illinois State Police Division of Forensic Services), state comptroller offices managing cooperative purchasing networks (Texas Comptroller of Public Accounts), and research universities (University of Mississippi, Texas Tech University). The Illinois State Police has posted multiple IFBs for comparison microscopes over recent months, indicating a repeat buyer with ongoing capital equipment needs across multiple forensic laboratory locations.

Recent activity concentrates in Illinois and Texas. The Illinois State Police Division of Forensic Services posted IFB 27-493ISP-ADMIN-B-53673 for dual-unit comparison microscopes equivalent to Leica FS M or LEEDS LCF 2 models, due September 18, 2026, with delivery required across six forensic science facilities (Chicago, Rockford, Morton, Belleville, Joliet, Springfield) and an initial three-year term extendable to ten years; a prior Illinois State Police IFB (26-493ISP-FOREN-B-51686) closed June 18, 2026, with identical scope and eight specified laboratory locations. The Texas Comptroller of Public Accounts opened Requisition 304T-27-490M2 on the Texas Cooperative Purchasing Network (TCPN) for multiple microscope types and accessories, due September 1, 2026, structured as an indefinite-quantity, requirements-type agreement enabling state and local agencies across Texas to access pre-negotiated unit pricing. Texas Tech University issued RFP 2026-1190 for Research and Development Goods and Services including microscope equipment, due April 30, 2026, evaluated on demonstrated ability (50 percent), compliance (15 percent), qualifications (15 percent), financial value (10 percent), and value-added options (10 percent). The University of Mississippi solicited bids for an FTIR Microscope Micro-sampling and Chemical Imaging System, closed June 18, 2026.
