Abstract
An optical imaging lens including a first lens element to a sixth lens element arranged in sequence from an object side to an image side along an optical axis is provided. The first lens element has negative refracting power, and a periphery region of the object-side surface thereof is convex. An optical axis region of the image-side surface of the second lens element is convex. An optical axis region of the object-side surface of the third lens element is concave. An optical axis region of the object-side surface of the fourth lens element is convex and a periphery region of the image-side surface thereof is concave. The optical imaging lens only has abovementioned six lens elements having refracting power, and satisfies the following condition expression: V4+V5+V6≤120.000. Furthermore, other optical imaging lenses are also provided.
