Title
(EN) Six-piece optical lens system
Abstract
(EN)

A six-piece optical lens system includes, in order from the object side to the image side: a first lens element with a negative refractive power has a concave image-side surface, a second lens element with a positive refractive power has a convex image-side surface, a third lens element with a positive refractive power has a convex object-side surface, a fourth lens element with a negative refractive power has a concave image-side surface, a fifth lens element with a positive refractive power has a convex object-side surface, and a sixth lens element with a negative refractive power has a concave image-side surface. Each of the first, second, fourth and sixth lens elements has at least one aspheric surface, and one of the third and fifth lens elements is made of glass. Thereby, such a system can be applied to a high resolution mobile phone.
