LENS MODULE

摘要

A lens module includes: a first lens including a convex object-side surface and a convex image-side surface; a second lens including a concave image-side surface; a third lens including a concave object-side surface; a fourth lens having negative refractive power, and including a concave object-side surface; and a fifth lens having negative refractive power and including an image-side surface having one or more inflection points and a convex object-side surface. The first lens, the second lens, the third lens, the fourth lens and the fifth lens are sequentially disposed in a direction from an object side of the lens module. The expression f/ImgH<1.3 is satisfied, with f being an overall focal length of an optical system including the first lens, the second lens, the third lens, the fourth lens and the fifth lens, and with ImgH being half of a diagonal length of an image sensor.
