The invention relates to an optical system, a camera module and an automobile. The optical system includes, in order from an object side to an image side: a first lens element with negative refractivepower having a convex object-side surface and a concave image-side surface; a second lens element with negative refractive power, wherein the image-side surface of the second lens element is concave;a third lens element with positive refractive power; a diaphragm; a fourth lens element with positive refractive power; a fifth lens element with negative refractive power; wherein the optical systemsatisfies the following relationship: (SD S2)/(RDY S2) < 0.93; the SD S2 is the Y-direction half aperture of the image side surface of the first lens, and the RDY S2 is the Y radius of the image sidesurface of the first lens. At the moment, the Y radius and the Y-direction semi-aperture of the image side surface of the first lens can be reasonably matched, so that the bending degree of the imageside surface of the first lens is effectively controlled, and the risk of ghosting is reduced.

    本申请涉及一种光学系统、摄像模组及汽车。光学系统由物侧至像侧依次包括:具有负屈折力的第一透镜,第一透镜的物侧面为凸面,像侧面为凹面;具有负屈折力的第二透镜,第二透镜的像侧面为凹面;具有正屈折力的第三透镜;光阑;具有正屈折力的第四透镜;具有负屈折力的第五透镜;光学系统满足关系:(SD S2)/(RDY S2)<0.93;其中,SD S2为第一透镜的像侧面的Y方向半孔径,RDY S2为第一透镜的像侧面的Y半径。此时,可合理匹配第一透镜的像侧面的Y半径及Y方向半孔径,以有效的控制第一透镜的像侧面的弯曲程度,减小产生鬼影的风险。
