ABSTRACT:
An imaging lens device has an imaging lens system that forms an optical image and an image sensing device that converts the optical image formed by the imaging lens system into an electronic signal. The imaging lens system includes two lens elements each made of a homogeneous material and having a positive optical power, and fulfills the following condition: 1.25<L/f<2.00, where L is the distance from the most object side lens surface to the image plane, and f is the overall focal length of the lens system.
