Key success of today’s mobile handsets and tablets is the increase of functionality by implementation of new sensors into the devices. Optical and imaging functions are considered core features and are realized using miniaturized or micro optics. In the last decade, micro optics manufacturing has reached a high level of confidence and is supposed to be one of the manufacturing technologies to address future requirements for even smaller and thinner devices. In this paper we will look at new processes like UV replication of micro lenses and precise placement and alignment technologies for imaging and LED optics. Manufacturing can be done on wafer level, as well as by a pick and place process. Results of printed micro lenses, as well as placement accuracy in active alignment processes will be shown.
