Description

Optical system and method of assembling an optical system Technical Field The present disclosure relates to an optical system and a method of assembling an optical system. Background With the development of technology, many electronic devices (such as tablet computers and smart phones) are currently equipped with an optical system. The user can take a photograph through the optical system. However, when the optical system is assembled, the photographing effect may be poor, for example, a shift in the center of a screen, unclear images, and the like, due to misalignment of the elements caused by an assembly tolerance accumulated between the elements. Therefore, active alignment (ACTIVE ALIGNMENT, AA) processes are widely used in the assembly of optical systems. In detail, the active alignment process can detect the actual position of the semi-finished product and adjust the position of the components to be assembled so that the relative positions of the components are aligned as much as possible.
