Abstract
An imaging lens includes first to sixth lens elements having refractive power and arranged in order from an object side to an image side along an optical axis of the imaging lens. Through designs of surfaces of the lens elements and relevant optical parameters, a short system length of the imaging lens may be achieved while maintaining good optical performance.
