摘要： An photographing optical lens assembly includes, in order from an object side to an image side, a first lens element with refractive power including a convex object-side surface, a second lens element with positive refractive power including a convex image-side surface, a third lens element with positive refractive power including a concave object-side surface and a convex image-side surface, a fourth lens element with negative refractive power, and a fifth lens element with positive refractive power including a convex object-side surface, a concave image-side surface and at least one inflection point. The surfaces of the fifth lens element are aspheric. By adjusting the photographing optical lens assembly, the total length of the photographing optical lens assembly is reduced, the aberration is corrected, and the image quality is improved.

摘要： An optical image collecting 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 through sixth lens elements all have refractive power. The fifth lens element has a concave object-side surface and a convex image-side surface, wherein at least one of the object-side surface and the image-side surface of the fifth lens element is aspheric. The sixth lens element has a concave image-side surface at a paraxial region, wherein the image-side surface of the sixth lens element changes from concave at the paraxial region to convex at a peripheral region, and both of an object-side surface and the image-side surface of the sixth lens element are aspheric.
