OPTICAL SYSTEM

An optical system is provided and includes a fixed module, a movable module, a driving assembly and a plurality of sliding members. The fixed module includes a base. The movable module includes an optical member holder and a driving frame unit. The optical member holder is configured to hold an optical member, and the driving frame unit is connected to the optical member holder. The driving assembly includes at least one first magnetic element and at least one second magnetic element. The second magnetic element corresponds to the first magnetic element and is configured to drive the driving frame unit with the optical member holder to move relative to the base. The sliding members are securely disposed on the fixed module or the movable module, so that the movable module is able to sliderelative to the fixed module. 本公开提供了种光学系统，包含固定部、活动部、驱动组件以及多个滑动元件。固定部包含底座。活动部包含有光学元件承载件以及驱动框架单元。光学元件承载件配置以承载光学元件，并且驱动框架单元连接于光学元件承载件。驱动组件包含至少第磁性元件以及至少第二磁性元件。第二磁性元件对应于第磁性元件，用以驱使驱动框架单元带动该光学元件承载件相对于该底座移动。多个滑动元件固定地设置于固定部与活动部两者其中之上，
