US Patent 9239447 Optical imaging lens assembly, image capturing unit and electronic device

An optical imaging 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, a fifth lens element, and a sixth lens element. The first lens element with positive refractive power in a paraxial region thereof has an object-side surface being convex in a paraxial region thereof. The second lens element has refractive power in a paraxial region. The third lens element has negative refractive power in a paraxial region thereof. The fourth lens element has negative refractive power in a paraxial region thereof. The fifth lens element has refractive power in a paraxial region thereof. The sixth lens element with positive refractive power in a paraxial region thereof has an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof.
