OPTICAL IMAGE CAPTURING SYSTEM

摘要

An optical image capturing system 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 and the third lens element have refractive power. The fourth lens element with negative refractive power has a concave object-side surface and a convex image-side surface. The fifth lens element with positive refractive power has a convex object-side surface, wherein at least one inflection point is on at least one surface thereof. The sixth lens element with negative refractive power has a concave object-side surface. The surfaces of the fifth and the sixth lens elements are aspheric. The optical image capturing system has a total of six lens elements.

1. An optical image capturing system comprising, in order from an object side to an image side:
a first lens element with positive refractive power having an object-side surface being convex at a paraxial region thereof; a second lens element; a third lens element; a fourth lens element, a fifth lens element with positive refractive power having an object-side surface being convex at a paraxial region thereof and an image-side surface being concave at a paraxial region thereof, wherein the object-side surface and the image-side surface of the fifth lens element are aspheric, and the fifth lens element has at least one inflection point on the image-side surface thereof; and a sixth lens element with negative refractive power having an object-side surface being concave at a paraxial region thereof and an image-side surface being concave at a paraxial region thereof, wherein the object-side surface and the image-side surface of the sixth lens element are aspheric; wherein the optical image capturing system has a total of six lens elements.
