Microsystems for Spectral Sensing

Unstoppable, spectral sensors and spectral imaging sensors are leaving the lab and aiming for field applications. The main driving forces include quality assurance in agriculture and the food industry, industrial process control and environmental monitoring. The requirements for high spectral resolution, a wide wavelength range, high efficiency and at the same time a compact design seem to contradict each other. The webinar, moderated by Robert Brunner, professor at the University of Applied Sciences Jena, focused on innovative solutions for miniaturized spectral and spectral imaging. The event covered sensors suitable for different wavelengths, especially for the NIR range >1µm, concepts for array optical imaging, manufacturing aspects and challenges related to environmental conditions in field applications.
