OPTICAL SYSTEM, CAMERA MODULE, AND ELECTRONIC DEVICE

WIPO Patent Application WO/2022/061510

A1

The present invention provides an optical system, a camera module, and an electronic device. The optical system comprises, in order from an object side to an image side along an optical axis: a prism; a first lens group having positive refractive power, the first lens group comprising a first lens; a second lens group having negative refractive power, the second lens group comprising a second lens, a third lens, and a fourth lens; and a third lens group having positive refractive power, the third lens group comprising a fifth lens, a sixth lens, and a seventh lens. Distances among the first lens group, the second lens group, and the third lens group can be adjusted so that the optical system is at a long focal end, a medium focal end, and a short focal end. The optical system has different focal lengths at the long focal end, the medium focal end, and the short focal end. The present invention solves the technical problem that existing lenses cannot simultaneously meet the requirements of large-range zoom and lens miniaturization.
