1. An imaging lens comprising:
- a body having a first opening and a second opening formed therein;
a first lens group disposed in the body so as to correspond to the first opening; and
a second lens group disposed in the body so as to correspond to the second opening,wherein a focal length of the first lens group is greater than 1.8 times a focal length of the second lens group and less than 2.1 times the focal length of the second lens group,wherein the first lens group is not overlapped with the second lens group in an optical axis direction,wherein the first lens group comprises first to fifth lenses arranged sequentially in a direction from an object side toward an image side and having refractive power, andwherein the first lens, the fourth lens, and the fifth lens have positive refractive power, and the second lens and the third lens have negative refractive power.

14. A camera module comprising:
-
an imaging lens comprising a body having a first opening and a second opening formed therein, a first lens group disposed in the body so as to correspond to the first opening, and a second lens group disposed in the body so as to correspond to the second opening, a focal length of the first lens group being greater than 1.8 times a focal length of the second lens group and less than 2.1 times the focal length of the second lens group; a filter for selectively transmitting light that has passed through the imaging lens depending on a wavelength of the light; and a light-receiving element for receiving light that has passed through the filter, wherein the first lens group is not overlapped with the second lens group in an optical axis direction, wherein the light-receiving element is an image sensor, and wherein at least one of a horizontal length or a vertical length of a unit pixel of the image sensor is 2 micrometers or less. - View Dependent Claims (15, 16, 17, 18, 19, 20)
