Imaging lens assembly

[0051]FIG. 1 is a schematic view of an imaging lens assembly according to the 1st embodiment of the present disclosure. FIG. 2 shows spherical aberration curves, astigmatic field curves and a distortion curve of the imaging lens assembly according to the 1st embodiment. In FIG. 1, the imaging lens assembly includes, in order from an object side to an image side, an aperture stop 100, a first lens element 110, a second lens element 120, a stop 101, a third lens element 130, a fourth lens element 140, a fifth lens element 150, a sixth lens element 160, an IR-cut filter 180 and an image plane 170, wherein the imaging lens assembly has a total of six non-cemented lens elements (110-160) with refractive power.

[0052]The first lens element 110 with positive refractive power has a convex object-side surface 111 and a concave image-side surface 112. The first lens element 110 is made of plastic material, and has the object-side surface 111 and the image-side surface 112 being both aspheric.
