[0075] see Figure 1 to Figure 4 , from the object side to the image side, the imaging lens 10 of the first embodiment includes an aperture STO, a first lens L1, a second lens L2, a third lens L3, a fourth lens L4, a fifth lens L5 and an infrared filter Slice L6.
[0076] The first lens L1 has positive refractive power and is made of plastic. The object side S1 is convex, and the image side S2 is concave at the optical axis and convex at the circumference, both of which are aspherical. The second lens L2 has a negative refractive power and is made of plastic. The object side S3 is convex, and the image side S4 is concave, both of which are aspherical. The third lens L3 has negative refractive power and is made of plastic. The object side S5 is concave, and the image side S6 is convex, both of which are aspherical. The fourth lens L4 has positive refractive power and is made of plastic. The object side S7 is convex at the optical axis and concave at the circumference, and the...
