Abstract

The invention provides a single focus lens having wide view angle. The single focus lens includes a first optical element with weak optical power, a second optical element with positive optical power, a third optical element with negative optical power, a fourth optical element with positive optical power and a fifth optical element with positive optical power in sequence from the object side to the image side. The single focus lens satisfies the following condition: 0 < |f23/f1| < 0.12, wherein f23 is the focal length of the second and third optical elements, and f1 is the focal length of the first optical element.
