Optical imaging systems, imaging units and electronic devices

Abstract

The invention relates to an optical imaging system comprising ten lens elements, in order from the object side to the image side along the optical path: the first lens element, the second lens element, the third lens element, the fourth lens element, the fifth lens element, the sixth lens element, the seventh lens element, the eighth lens element, the ninth lens element, and the tenth lens element. Each of the ten lens elements has an object-facing surface and an image-facing surface. The second lens element has negative refractive power. The tenth lens element has negative refractive power, and at least one of the object-facing and image-facing surfaces of the tenth lens element has at least one inflection point. Furthermore, the invention refers to a photographic component including this optical imaging system, and an electronic device comprising at least two such photographic components.
