US Patent 9348117 Photographing optical lens assembly, image capturing unit and electronic device

A photographing optical lens assembly includes, in order from an object side to an image side, a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element. The first lens element with positive refractive power has a convex object-side surface, wherein the object-side surface and an image-side surface thereof are aspheric. The second lens element has negative refractive power, wherein an object-side surface and an image-side surface thereof are aspheric. The third lens element has refractive power, wherein an object-side surface and an image-side surface thereof are aspheric. The fourth lens element has positive refractive power, wherein an object-side surface and an image-side surface thereof are aspheric. The fifth lens element with negative refractive power has a concave image-side surface, wherein an object-side surface and the image-side surface thereof are aspheric.
