In the FOWINA project, the Fraunhofer Institute for Integrated Circuits IIS in Erlangen and the Fraunhofer Institute for Silicate Research ISC in Würzburg have developed novel color sensors with a special microlens arrangement. The sensors can be realized directly on the chip and combine multiple functions in a minimum of space. Their extremely slim design makes the sensors suitable for a wide range of applications, such as in mobile devices or color-adjustable LED lamps.
