Optical technologies continuously penetrate into our everyday life and enable new functionalities in consumer electronic devices, medical, industrial and automotive applications. Specifically optical sensors are a key enabling technology for new applications like self-driving cars, extended reality, mobile optical sensing and analytics. The talk will focus on current and future challenges for optical thin film interference filters to match the technical and cost requirements while producing high volume. The combination of applying high precise and uniform thin film coatings on optical glass substrates or structured CMOS wafers at highest yields and lowest costs are mandatory.
