Abstract
Official abstract text for this publication.
An image lens, in the order from the object side to the image side thereof, includes a first lens including a first surface and a second surface, a second lens including a third surface and a fourth surface, a third lens including a fifth surface and a sixth surface, a fourth lens including a seventh surface and a eighth surface, a fifth lens including a ninth surface and a tenth surface, and an image plane. The image lens satisfies the following formulas: (1) D/TTL>0.94; (2) D/L>1.21; wherein D is the maximum image diameter of the image plane; TTL is a total length of the image lens, and L is a distance from an outmost edge of the tenth surface to an optical axis of the image lens along a direction perpendicular to the optical axis.
