Lens module
A lens module includes first to seventh lenses each having refractive power and sequentially disposed in numerical order from the first lens to the seventh lens starting from an object side of the lens module, wherein each of the first and second lenses has a meniscus shape and an image-side surface that is convex, and the seventh lens has one or more inflection points on an image-side surface thereof.
1 . A lens module comprising:
a first lens having positive refractive power;
a second lens having negative refractive power;
a third lens having a convex object-side surface;
a fourth lens having a convex object-side surface;
a fifth lens having negative refractive power;
a sixth lens having a refractive power; and
a seventh lens having negative refractive power,
wherein the first to seventh lenses are sequentially disposed in numerical order from an object side of the lens module,
wherein 80°<FOV, where FOV is a field of view of the lens module, and wherein a thickness of the sixth lens is greater than a thickness of the third lens.
2 . The lens module of claim 1 , wherein the third lens has a convex image-side surface.
3 . The lens module of claim 1 , wherein the seventh lens has a concave image-side surface.
4 . The lens module of claim 1 , wherein an f number of the lens module is 2.2 or less.
5 . The lens module of claim 1 , wherein the fifth lens has a concave object-side surface.
6 . A lens module comprising:
a first lens having positive refractive power;
a second lens having negative refractive power;
a third lens having a convex object-side surface;
a fourth lens having a concave image-side surface;
a fifth lens having negative refractive power;
a sixth lens having a refractive power; and
a seventh lens having negative refractive power,
wherein the first to seventh lenses are sequentially disposed in numerical order from an object side of the lens module,
wherein a thickness along an optical axis of the fifth lens is greater than a thickness along an optical axis of the fourth lens,
wherein 80°<FOV, where FOV is a field of view of the lens module, and
wherein a thickness of the sixth lens is greater than a thickness of the third lens.
7 . The lens module of claim 6 , wherein the third lens has a convex image-side surface.
8 . The lens module of claim 6 , wherein the seventh lens has a concave image-side surface.
9 . The lens module of claim 6 , wherein an f number of the lens module is 2.2 or less.
