Abstract:
This disclosure provides an imaging lens system including, in order from an object side to an image side: a first lens element with positive refractive power having an object-side surface being convex in a paraxial region thereof; a second lens element with negative refractive power; a third lens element with refractive power, wherein an object-side surface and an image-side surface thereof are aspheric; a fourth lens element with refractive power, wherein an object-side surface and an image-side surface thereof are aspheric; and a fifth lens element with negative refractive power having an object-side surface being concave in a paraxial region thereof and an image-side surface being convex in a paraxial region thereof, which are both aspheric. The imaging lens system is further provided with an aperture stop, and there is no lens element with refractive power disposed between the aperture stop and the first lens element.

Claim (Index 20):
An imaging lens system comprising five lens elements, the five lens elements being, in order from an object side to an image side: a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element;\n wherein each of the five lens elements comprises an object-side surface facing toward the object side and an image-side surface facing toward the image side, at least one of the five lens elements comprises at least one aspheric surface, a central thickness of the first lens element is the largest among central thicknesses of all the lens elements, an axial distance between the fourth lens element and the fifth lens element is the largest among all axial distances between adjacent lens elements, the first lens element has positive refractive power, the second lens element has negative refractive power, the object-side surface of the second lens element is convex in a paraxial region thereof and the image-side surface of the second lens element is concave in a paraxial region thereof; wherein an axial distance between the object-side surface of the first lens element and an image surface is TL, a focal length of the imaging lens system is f, a maximum refractive index among refractive indices of the first lens element, the second lens element, the third lens element, the fourth lens element and the fifth lens element is Nmax, and the following conditions are satisfied:\n 0.75< TL/f< 1.0; \n 1.50< N max<1.70.
