OPTICAL IMAGING LENS AND ELECTRONIC DEVICE COMPRISING THE SAME

摘要

An optical imaging lens set includes a first lens element having an image-side surface with a convex part in a vicinity of its periphery, a second lens element with negative refractive power having an image-side surface with a concave part in a vicinity of the optical axis, a third lens element having an object-side surface with a concave part in a vicinity of the optical axis, a fourth lens element having an image-side surface with a convex part in a vicinity of the optical axis, a fifth lens element having an image-side surface with a concave part in a vicinity of the optical axis, and a sixth lens element having an image-side surface with a convex part in a vicinity of its periphery. The optical imaging lens set does not include any lens element with refractive power other than said first, second, third, fourth, fifth and sixth lens elements.
