Abstract

An imaging lens system, from an object side to an imaging plane, sequentially includes: a flat glass; a first lens with a negative focal power, a convex object side surface and a concave image side surface; a second lens with a positive focal power, a convex object side surface and a concave image side surface; a stop; a third lens with a positive focal power and a convex image side surface. The imaging lens system meets expressions: f/EPD≤1.64; 0<BFL/IH<0.2; where f represents an effective focal length of the imaging lens system, and EPD represents an entrance pupil diameter of the imaging lens system; BFL represents a distance from a vertex of the image side surface of the third lens to the imaging plane on the optical axis, and IH represents the maximum image height of the imaging lens system.
