Abstract

The invention relates to the technical field of optical imaging, in particular to an optical imaging system, an image capturing module, electronic equipment and an automobile. The optical imaging system sequentially comprises: a first lens with negative refractive power; a second lens with negative refractive power which has an image-side surface being concave in a paraxial region thereof; a third lens with positive refractive power which has an object-side surface and an image-side surface being convex in a paraxial region thereof; a fourth lens with positive refractive power which has an object-side surface being concave in a paraxial region thereof; a fifth lens with positive refractive power which has an object-side surface and an image-side surface being convex in a paraxial region thereof; and a sixth lens with negative refractive power which has an object-side surface being concave in a paraxial region thereof. The optical imaging system satisfies the following conditional expression: 14 mm < f1 * f2 / f < 17 mm. According to the optical imaging system, the imaging resolution of the system can be improved, and an imaging result with a large visual angle and high resolution can be obtained.

Description

technical field [0001] The present application relates to the technical field of optical imaging, in particular to an optical imaging system, imaging module, electronic equipment and automobile. Background technique [0002] Family cars have multiple visual blind spots due to institutional constraints, while large trucks have even larger blind spots. Since the driver cannot see the road conditions in the blind spots while driving, the risk of traffic accidents due to the existence of visual blind spots is greatly increased. [0003] The existing car rearview mirror can only observe the road conditions on both sides of the car body, and its field of view is small, and it cannot completely collect all the information around the car body, especially when the car enters the main road from the side road, it passes through the left The rearview mirror cannot observe the situation of vehicles coming from behind the main road in real time. If the driver accelerates and cuts into th...
