Abstract: An imaging lens system includes a lens and a transparent plate. The lens is disposed between an object and a sensor, and the lens includes a flat surface facing the object and an aspheric surface facing the sensor. The transparent plate is connected to the lens and disposed between the object and the lens. An abbe number of the lens is in a range from 30 to 50, an abbe number of the transparent plate is in a range from 40 to 60, and an effective focal length (EFL) of the imaging lens system is in a range from about 0.3 millimeters to about 0.4 millimeters.
