Abstract
Embodiments of the present disclosure provide an optical imaging lens assembly that comprising, sequentially from an object side to an image side of the optical imaging lens assembly along an optical axis: a first lens having a negative refractive power, an object side surface of the first lens is convex surface and an image side surface of the first lens is a concave surface; a stop; a second lens having a positive refractive power, an object side surface of the second lens is a concave surface and an image side surface of the second lens is a convex surface; a third lens having a refractive power; a fourth lens having a refractive power, an object side surface of the fourth lens is a concave surface and an image side surface of the fourth lens is a convex surface. A relative illuminance RI corresponding to a maximal field-of-view of the optical imaging lens assembly satisfies: RI≥50%; and at least one of the first lens to the fifth lens is a lens made of plastic material.
