Abstract
The present disclosure discloses an optical imaging lens group including, sequentially from an object side to an image side along an optical axis, a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens. The first lens has a refractive power, an object-side surface of the first lens is a concave surface, and an image-side surface of the first lens is a convex surface; the second lens has a positive refractive power; the third lens has a negative refractive power; the fourth lens has a refractive power; the fifth lens has a negative refractive power, and the sixth lens has a refractive power. An effective focal length f2 of the second lens and a radius of curvature R3 of an object-side surface of the second lens satisfy 1.5<f2/R3<2.
