Abstract

An optical imaging lens includes a first lens element to a seventh lens element, and each lens element has an object-side surface and an image-side surface. The second lens element has negative refracting power, a periphery region of the object-side surface of the third lens element is concave, an optical axis region of the image-side surface of the third lens element is convex, the fifth lens element has positive refracting power, an optical axis region of the image-side surface of the fifth lens element is convex, an optical axis region of the image-side surface of the sixth lens element is concave, an optical axis region of the image-side surface of the seventh lens element is concave, a periphery region of the image-side surface of the seventh lens element is convex. The optical imaging lens satisfies the following conditions: D11t42/AAG37≤1.700 and D11t31/G34≤12.000.
