Abstract

The invention provides an optical pick-up system with wide view angle. The optical pick-up system includes a first optical element with negative optical power, a second optical element with positive optical power and a third optical element with negative optical power in sequence from the object side to the image side. The optical pick-up system satisfies the following condition: wherein fp1 is the focal length of the second optical element and ft is the focal length of the optical pick-up system.
