This invention provides an all-glass vehicle-mounted day and night confocal optical system and its application camera module, mainly composed of 8 lenses. The first lens has negative optical power, a convex object side, and a concave image side; the second lens has negative optical power, a concave object side, and a convex image side; the third lens has positive optical power, a convex object side, and a concave image side; the fourth lens has negative optical power, a convex object side, and a concave image side; the fifth lens has positive optical power, a convex object side, and a convex image side; the fourth and fifth lenses form a bonded lens; the sixth lens has positive optical power, a convex object side, and a convex image side; the seventh lens has negative optical power and a concave image side; and the eighth lens has optical power and a concave image side. The structure is simple and has advantages such as high resolution, large target area, small size, high relative illumination, and high pixel imaging, improving the uniformity of image illumination and image clarity.
