Optical system

An optical system, comprising:

• a movable part for holding an optical element that defines an optical axis;
• a fixed module, movably connected to the movable part and having a base;
• a driving assembly, driving the movable part to move relative to the fixed module;
• a position sensor, disposed on the base for detecting a position of the movable part relative to the fixed module;
• an electronic element disposed on the base, wherein the position sensor overlaps the electronic element when viewed along the optical axis;
• a resilient member, wherein the fixed module further has a housing connected to the base, and the base has a bottom surface parallel to the optical axis, a pillar forming a first surface not parallel to the optical axis, and a wall connecting to the pillar and forming a depressed structure for receiving a part of the driving assembly, wherein the resilient member is disposed on the first surface and movably connects a holder with the fixed module;
• and
• a conductive member, wherein a part of the conductive member is embedded in the wall and electrically connected to the driving assembly, and the conductive member has an end surface exposed to a side of the wall and electrically connected to a conductive pad of the driving assembly, wherein the end surface is not parallel to the conductive pad.
