Description

Optical system Technical Field The present invention relates to an optical system, and more particularly, to an optical system having a plurality of optical modules and a flexible portion. Background With the development of technology, many electronic devices (such as computers or tablet computers) have a function of photographing or recording. The use of these electronic devices is becoming more common, and more stable and better optical quality is being developed, and more convenient and light-weight designs are being developed to provide more options for users. However, when an optical element (e.g., a lens) with a long focal length is required to be disposed in the electronic device, the thickness of the electronic device is increased, which is disadvantageous for the light weight and the stability of the electronic device. In addition, due to different imaging requirements, the electronic devices are required to have functions of optical shake prevention, focal length adjustment, light incoming amount and the like. However, motors with different functions are not necessarily matched with each other. In view of this, how to design an optical system that can make an electronic device light, thin and stable, and has better compatibility, and can be matched with more modules has become an important issue.
