Abstract

The invention relates to a method of producing a movable lens structure that comprises the steps of: forming a lens from a lens material disposed on a carrier of another material (step 58), and forming a micromechanical structure from the carrier (step 60), wherein the forming of the lens takes place before the forming of the micromechanical structure. With this method a simplified production method is obtained that simplifies difficult compatibility requirements between micromechanics and lens that can otherwise be hard to meet.
