CAMERA DEVICE AND OPTICAL IMAGING LENS THEREOF

摘要

The present invention provides a camera device and an optical imaging lens thereof. The optical imaging lens comprises five lens elements positioned in an order from an object side to an image side. Through controlling the convex or concave shape of the surfaces of the lens elements, the view angle of the optical imaging lens is efficiently increased to provide better optical characteristics.

主权项

1. An optical imaging lens, sequentially from an object side to an image side along an optical axis, comprising first, second, third, fourth and fifth lens elements, each of said first, second, third, fourth and fifth lens elements having refracting power, an object-side surface facing toward the object side and an image-side surface facing toward the image side, wherein:
said object-side surface of said first lens element comprises a convex portion in a vicinity of the optical axis; said image-side surface of said second lens element comprises a concave portion in a vicinity of a periphery of the second lens element; said image-side surface of said third lens element comprises a convex portion in a vicinity of the optical axis; said image-side surface of said fourth lens element comprises a concave portion in a vicinity of the optical axis; and said image-side surface of said fifth lens element comprises a convex portion in a vicinity of the optical axis.
