OPTICAL IMAGING LENS AND ELECTRONIC DEVICE COMPRISING THE SAME

摘要

An optical imaging lens includes first, second, third, fourth, fifth and sixth lens elements arranged in order from the object side to the image side. The first lens element has an image-side surface with a concave part in a vicinity of its periphery, the second lens element has an image-side surface with a concave part in a vicinity of the optical axis, the third lens element has positive refractive power, the fourth lens element has an object-side surface with a convex part in a vicinity of its periphery, the fifth lens element has an object-side surface with a concave part in a vicinity of the optical axis, the sixth lens element has an image-side surface with a concave part in a vicinity of the optical axis. The second lens element has negative refractive power. The sixth lens element has positive refractive power.
