    Abstract: An optical system includes a base, a first lens driving module, and a second lens driving module. The first lens driving module includes a first lens holder, a first magnet, and a first coil. The first lens holder is configured to hold a first optical element. The first coil corresponding to the first magnet is configured to drive the first lens holder to move relative to the base. The second lens driving module includes a second lens holder, a second magnet, and a second coil. The second lens holder is configured to hold a second optical element. The second coil corresponding to the second magnet is configured to drive the second lens holder to move relative to the base. The first magnet is disposed between the first and second lens holders, and no other magnet is disposed between the first and second lens holders except the first magnet.

    Abstract: An optical element driving mechanism is provided. The optical element driving mechanism includes a case, a bottom, a holder, a driving assembly, and a position sensing assembly. The bottom is connected to the case. The holder is disposed on the bottom and holds an optical element with an optical axis. The driving assembly drives the holder to move. The position sensing assembly senses the holder. The position sensing assembly includes a magnetic element, a sensor, and a magnetic-permeable element. The magnetic element is disposed on the holder. The sensor senses the magnetic element. The magnetic-permeable element is disposed adjacent to the sensor. The magnetic element and the sensor are arranged along a first direction. The sensor and the magnetic-permeable element are arranged along a second direction. The first direction is different from the second direction.
