UNSPSC 31241803: Infrared filters

UNSPSC 31241803 Infrared filters, a Commodity code, covers optical filtering components designed to transmit or block infrared radiation in specific wavelength ranges for thermal imaging, sensing, and detection applications. State and local governments procure infrared filters primarily for public safety and emergency response equipment—thermal imaging cameras used by fire departments, law enforcement, and emergency management agencies for search-and-rescue operations, building inspections, and hazmat response. The filters serve as precision optical components integrated into thermal camera systems and standalone thermal detection equipment operated by municipal fire services, county sheriff's offices, and state emergency response teams.

The source contains no recent state and local procurement opportunities tagged to this code. No issuing bodies, response dates, or representative solicitations are present in the available records for infrared filters. Given the specialized nature of the product and its narrow end-use in emergency services equipment, procurement under this Commodity code appears episodic rather than routine, with activity likely clustered among fire departments and public safety agencies when thermal imaging systems require replacement or upgrade.
