Abstract
An optical imaging lens includes a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element and a seventh lens element arranged in order from an object side to an image side along an optical axis. Each lens element has an object-side surface and an image-side surface. The first lens element has positive refracting power, and the image-side surface of the first lens element has a concave portion in a vicinity of a periphery. The third lens element has negative refracting power, and the image-side surface of the third lens element has a concave portion in a vicinity of a periphery. At least one of the object-side surface and the image-side surface of the fourth lens element is aspheric surface, and at least one of the object-side surface and the image-side surface of the fifth lens element is aspheric surface. The sixth lens element has positive refracting power, and the image-side surface of the seventh lens element has a concave portion in a vicinity of the optical axis.
