When the ESA Earth observation mission FLEX launches into space on September 15, 2026, as scheduled, it will carry high-precision optical components from Jena, Germany. Researchers at the Fraunhofer Institute for Applied Optics and Precision Engineering IOF have developed and manufactured a silicon-based double-slit assembly as well as two high-precision mirrors for the spectrometer on board the satellite. The spectrometer is designed to detect the fluorescence of plants excited by sunlight from Earth's orbit. The data is expected to provide new insights into the photosynthetic activity, health, and stress levels of vegetation.
