More Information
Summary:An optical imaging system includes a first lens group, a second lens group, a third lens group, and a fourth lens group sequentially disposed in ascending numerical order along an optical axis of the optical imaging system from an object side of the optical imaging system toward an imaging plane of the optical imaging system, wherein at least one lens group among the first lens group to the fourth lens group is configured to be movable along the optical axis, the first lens group has a positive refractive power and comprises a reflective member and at least one lens disposed between the object side of the optical imaging system and the reflective member, and the at least one lens is configured to refract light passing through the at least one lens to converge the light to be incident on the reflective member.
