OPTICAL IMAGING LENS ASSEMBLY AND IMAGE CAPTURING DEVICE

摘要

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 has a convex object-side surface. The second lens element with negative refractive power has a concave object-side surface and a convex image-side surface. The third lens element and the fourth lens element both have refractive power. The fifth lens element has refractive power, wherein both of the surfaces thereof are aspheric. The sixth lens element with negative refractive power has a concave object-side surface and a concave image-side surface, wherein the surfaces thereof are aspheric. The optical imaging lens assembly has a total of six lens elements with refractive power.
