Abstract:
A lens assembly, a fingerprint recognition apparatus and an electronic device. The lens assembly comprises, in order from an object side to an image side, a first lens (31) and a second lens (32). The first lens comprises a first lens element having negative focal power. The first lens element is an S-shaped lens element having a convex object-side surface. At least one of two surfaces of the first lens element is aspheric. The second lens comprises a second lens element having positive focal power. The second lens element has two convex surfaces. At least one of the two surfaces of the second lens element is aspheric. Parameters of the lens assembly satisfy a first relationship, such that a field of view (FOV) of the lens assembly is greater than a first threshold.
