Abstract
An optical imaging lens group includes, 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, a sixth lens and a seventh lens. The first lens has positive refractive power, and both an object-side surface and an image-side surface thereof are convex; the second lens has refractive power, and an object-side surface thereof is convex; the third lens has refractive power, and an object-side surface thereof is concave; the fourth lens has refractive power; the fifth lens has refractive power; the sixth lens has refractive power, and an object-side surface thereof is convex; and the seventh lens has negative refractive power. An edge thickness ETof the sixth lens and a center thickness CTof the sixth lens along the optical axis satisfy 0.2<ET/CT<0.9.
