Abstract
The disclosure provides an optical imaging lens assembly and a fingerprint identification device with the optical imaging lens assembly. The optical imaging lens assembly sequentially comprises, from an object side to an image side along an optical axis: a first lens with a negative refractive power, an object-side surface thereof being a concave surface; a second lens with a positive refractive power, an object-side surface thereof being a convex surface; and a third lens with a positive refractive power, an object-side surface thereof being a convex surface while an image-side surface being a convex surface. EPD is an entrance pupil diameter of the optical imaging lens assembly, and a total effective focal length f of the optical imaging lens assembly and EPD meet f/EPD<1.65. FOV is a maximum field of view of the optical imaging lens assembly, and FOV meets 125°<FOV<140°.
