Large-aperture, high-pixel optical system and camera module used thereby
A large-aperture, high-pixel optical system has six lenses arranged successively from its object side to its image side along its optic axis. The first lens has a convex surface facing the object side and a concave surface facing the image side; The third lens is biconcave; the second and fifth lenses are biconvex; the fourth and sixth lenses each have a concave surface facing the object side and a convex surface facing the image side. The fifth lens and the sixth lens form a combined lens and the optical system satisfies TTL/EFL≤4.5. Also disclosed is a camera module using the system. The system and the module are mainly composed of six lenses. Since the number of lenses used is limited, the structure is simple.
