This company, a member of the BYK Additives & Instruments division of ALTANA, offers a new instrument to objectively detect and quantify fluorescent light excited in the visible range: the BYK-mac i spectrophotometer. The instrument is equipped with additional out-of-plane sensors that can measure the fluorescent light in clearly defined wavelength ranges. To quantify the fluorescent light, BYK-mac i reportedly calculates a new index known as the “Intensity Emission value,” which can be used as a preliminary indicator for light fastness.

Due to the highly stable LED illumination, fluorescent color measurements can reportedly now be repeatable with one BYK-mac (no warm-up time, no temperature drift) and reproducible from BYK-mac to BYK-mac (no lamp aging). This allows usage of digital standards among the complete supply chain, which is a  key to global color QC management.
