Abstract

The present disclosure discloses an optical imaging lens assembly 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, a sixth lens and a seventh lens. At least one of the first lens to the seventh lens is a glass lens. The third lens has positive refractive power, and an image-side surface of the third lens is a convex surface. An object-side surface of the seventh lens is a convex surface, and an image-side surface of the seventh lens is a concave surface. A maximum field-of-view FOV of the optical imaging lens assembly satisfies FOV≥134.56°. An effective half-aperture DT62 of an image-side surface of the sixth lens and an effective half-aperture DT72 of the image-side surface of the seventh lens satisfy 0.54≤DT62/DT72.
