Abstract
The present invention provides a camera device and an optical imaging lens thereof. The optical imaging lens comprises six 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 shows better optical characteristics.
Claims16
An optical imaging lens, sequentially from an object side to an image side along an optical axis, comprising a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element, each of said first, second, third, fourth, fifth and sixth 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 first lens element has negative refracting power;
