News Summary

• Researchers at the University of Cambridge and GlitterinTech have developed a new type of optical spectrometer that combines exceptional accuracy with a remarkably small size and low cost.
• Measuring just centimeters across, the device could be incorporated into portable electronics and wearable health technology.
• Its potential applications range from monitoring important health markers in real time to identifying materials and detecting changes in chemical composition.
• The technology could also transform food testing, industrial quality control, and environmental monitoring, the researchers say.
• The new device uses a mathematical principle called the convolution theorem to analyze light in a fundamentally different way.
