Imaging lens

#Field of the Invention

#The present invention relates to imaging lenses which form an image of an object on a solid-state image sensor such as a CCD sensor or a C-MOS sensor used in a compact image pickup device. More particularly, the invention relates to imaging lenses which are built in image pickup devices mounted in highly functional products such as smart TVs and 4K TVs, information terminals such as game consoles and PCs, and mobile terminals such as smart phones, mobile phones and PDAs (Personal Digital Assistants).

#Description of the Related Art

#FIG. 1 is a schematic view showing the general configuration of an imaging lens in Example 1;

#FIG. 2 shows spherical aberration, astigmatism, and distortion of the imaging lens in Example 1;

#FIG. 3 is a schematic view showing the general configuration of an imaging lens in Example 2;

#Hereinafter, the preferred embodiment of the present invention will be described in detail referring to the accompanying drawings.

#FIGS. 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, and 21 are schematic views showing the general configurations of the imaging lenses according to Examples 1 to 11 of this embodiment respectively. Since all these examples have the same basic configuration, the general configuration of an imaging lens according to this embodiment is explained below referring to the schematic view of Example 1.

#As shown in FIG. 1, the imaging lens according to this embodiment includes an aperture stop ST, a first lens L1 with positive refractive power, a second lens L2 with negative refractive power, a third lens L3 with positive refractive power, a fourth lens L4 with positive refractive power, a fifth lens L5 with negative refractive power, and a sixth lens L6 with negative refractive power which are arranged in order from an object side to an image side.
