For a long time, hyperspectral imaging was considered complex and space-consuming. New technologies are, however, now paving the way for compact and efficient solutions. Interference filters that can be integrated directly into CMOS image sensors enable customized spectral analyses in the smallest of spaces. They thereby open up new application possibilities in environmental monitoring, agriculture and industrial quality assurance. The Fraunhofer Institute for Surface Engineering and Thin Films IST will be providing an insight into this key optical-sensor technology on the Fraunhofer joint stand at this year’s LASER World of Photonics in Munich.
