OPTICAL IMAGING SYSTEM

Abstract: an optical imaging system includes an optical system including at least six lenses, sequentially disposed from an object side toward an image side, an image sensor configured to convert light incident through the optical system into an electronic signal, and a variable stop configured to change an incident hole diameter and disposed toward the object side of a lens of the optical system closest to the object side, wherein ttl is a distance to an imaging plane of the image sensor from an object-side surface of the lens closest to the object side and 4.7 mm<ttl<6.00 mm, and ri is a radius of curvature of an object-side surface of a lens of the optical system second closest to the image sensor, rj is a radius of curvature of an image-side surface of the lens second closest to the image sensor, and −0.5<(|ri|−|rj|)/(|ri|+|rj|)<0.5.
