Title:
OPTICAL IMAGING SYSTEM, IMAGING MODULE, ELECTRONIC DEVICE AND DRIVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/189463
Kind Code:
A1
Abstract:
Provided is an optical imaging system. The optical imaging system (100) sequentially comprises, from an object side to an image side along an optical axis, a first lens group having a negative refractive power; a second lens group having a positive refractive power; a third lens group having a positive refractive power; a fourth lens group having a positive refractive power; and a diaphragm arranged on the object side of the third lens group. According to the optical imaging system (100), the lenses in the system are divided into groups such that the system can achieve both a wide viewing angle and a high resolution capability, and also has the characteristic of miniaturization. An imaging module comprising the optical imaging system, and an electronic device and a driving device comprising the imaging module are further provided.
