Abstract
An optical lens system includes two lens elements which are, in order from an object side to an image side along an optical path: a first lens element and a second lens element. Each of the two lens elements has an object-side surface facing toward the object side and an image-side surface facing toward the image side. At least one of the object-side surface and the image-side surface of at least one lens element of the optical lens system is aspheric. A total number of the lens elements in the optical lens system is two.
