Optical system

An optical system comprises a bearing piece, a fixing module, a driving assembly and a first elastic element. Wherein the bearing piece is used for bearing an optical element with an optical axis, andthe fixing module is movably connected with the bearing piece and is provided with a shell and a base which are connected with each other. The base is provided with a bottom face parallel to the optical axis and a first protruding column, and the first protruding column is provided with a first surface which is not parallel to the bottom face. The driving assembly is used for driving the bearingpiece to move relative to the fixing module. The first elastic element is arranged on the first surface and movably connected with the bearing piece and the fixing module. 一种光学系统，包括一承载件、一固定模块、一驱动组件以及一第一弹性元件。前述承载件用以承载具有一光轴的一光学元件，前述固定模块活动地连接前述承载件，并且具有相互连接的一外壳以及一底座。前述底座具有与前述光轴平行的一底面以及一第一凸柱，且前述第一凸柱具有与前述底面不平行的一第一表面。前述驱动组件用以驱动前述承载件相对前述固定模块运动。前述第一弹性元件设置于前述第一表面上，并活动地连接前述承载件以及前述固定模块。
