Abstract
The present disclosure discloses an optical imaging lens assembly including a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens sequentially from an object side to an image side along an optical axis. Each of the first lens and the fifth lens has a positive refractive power. Each of the second lens, the third lens, and the fourth lens has a positive refractive power or a negative refractive power. An object-side surface of the first lens and an image-side surface of the fifth lens are convex surfaces. An image-side surface of the second lens, an object-side surface of the sixth lens, and an image-side surface of the sixth lens are concave surfaces. A total effective focal length f of the optical imaging lens assembly and an entrance pupil diameter EPD of the optical imaging lens assembly satisfy: f/EPD≤1.8.
