Claim 0:
1. A lens assembly comprising:
a first lens array comprising a plurality of first lenses, the plurality of first lenses respectively having positive refractive power and being provided in a direction perpendicular to an optical axis of the lens assembly;
a second lens array comprising a plurality of second lenses, the plurality of second lenses respectively having negative refractive power and being provided in the direction perpendicular to the optical axis of the lens assembly; and
a third lens array comprising a plurality of third lenses, the plurality of third lenses respectively having negative refractive power and being provided in the direction perpendicular to the optical axis of the lens assembly,
wherein the first lens array, the second lens array, and the third lens array are sequentially arranged from an object side toward an image sensor side,
wherein each first lens of the plurality of first lenses has a biconvex shape that is convex toward the object side and convex toward the image sensor side,
wherein each second lens of the plurality of second lenses and each third lens of the plurality of third lenses has a meniscus shape that is convex toward the image sensor side, and
wherein a focal length of each second lens of the plurality of second lenses is f2 and a focal length of each third lens of the plurality of third lenses is f3, and a power configuration of the lens assembly satisfies:

1.6<(1/f3)/(1/f2)<2.5.
