The optical system enables a miniaturized design and wide-angle characteristics.

Description

technical field [0001] The invention relates to the field of imaging, in particular to an optical system, an imaging module and an electronic device. Background technique [0002] With the rapid development of camera technology, more and more electronic devices such as smart phones, tablet computers, and e-readers are equipped with optical systems to realize camera functions. Users' requirements for optical systems are also getting higher and higher, not only requiring the optical system to have good imaging quality, but also requiring the optical system to have a small size to meet the needs of the miniaturized design of electronic devices and improve the experience of using electronic devices. However, the size of the current optical system still needs to be reduced, and it is difficult to meet the requirements of miniaturized design of electronic equipment. SUMMARY OF THE INVENTION [0003] Based on this, it is necessary to provide an optical system, an imaging module ...
