The research group of Cluster PI Uli Lemmer at the Light Technology Institute of KIT demonstrates at the Hannover Messe 2023 how optical filters and dielectric mirrors can be manufactured in a customized, cost-effective, and energy-saving way via inkjet printing. They present their new manufacturing process based on new materials and inks from April 17 to 21 at their booth. The researchers see a high demand for the printed filters and mirrors in medicine, metrological devices, telescopes and microscopes, camera systems, sensor systems and solar panels.
