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 12):
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, and a central thickness of the first lens element is the largest among central thicknesses of all the lens elements; wherein the third lens element has at least one inflection point; 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 half of maximal field of view of the imaging lens system is HFOV, 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, an axial distance between the second lens element and the third lens element is T23, an axial distance between the third lens element and the fourth lens element is T34, an axial distance between the fourth lens element and the fifth lens element is T45, and the following conditions are satisfied:\n 0.75< TL/f< 1.0; \n 0.3<tan(2*HFOV)<1.0; \n 1.639\u2264 N max<1.70; and \n 0.5<( T 23+ T 45)/ T 34<6.0.
