UNSPSC 31241808: Dichroic filter

A dichroic filter or thin-film filter is a very accurate color filter used to selectively pass light of a small range of colors while reflecting other colors

UNSPSC 31241808 Dichroic filter is a Commodity code covering optical filters used to separate or reflect specific wavelengths of light in imaging, spectroscopy, and instrumentation applications. State and local governments procure dichroic filters primarily through purchases tied to scientific equipment, medical diagnostic systems, laboratory instruments, and specialized imaging apparatus. The filters support work in public health laboratories, university research facilities, environmental monitoring stations, and hospital diagnostic departments where wavelength-selective optical performance is essential to equipment function.

The source provides no records of recent state and local solicitations under this code, making it difficult to characterize active issuing bodies, geographic concentration, or representative opportunities at this time. The Commodity code appears to see limited standalone procurement activity in the state and local market, with most acquisitions likely embedded within larger equipment or system procurements tagged to parent Family or Class codes rather than to the specific filter component itself.
