    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 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 slide relative to the fixed module.

    Abstract: An electromagnetic driving mechanism is provided, including a housing, a circuit unit, an electromagnetic driving assembly, and a sensing element. The circuit unit is connected to the housing, and has a plastic material and a circuit element. The plastic material is formed on and covers an outer surface of the circuit element by insert molding. The electromagnetic driving assembly is disposed in the housing for forcing an optical element to move relative to the circuit unit. The sensing element is disposed on the circuit unit, and electrically connected to the circuit element for detecting the displacement of the optical element relative to the circuit unit.
