Abstract: An optical system is provided, including a holder, a fixed module, a driving assembly, and a first resilient member. The holder is used for holding an optical element that defines an optical axis. The fixed module is movably connected to the holder and has a housing and a base connected to the housing. The base has a bottom surface parallel to the optical axis and a first pillar forming a first surface not parallel to the optical axis. The driving assembly drives the holder to move relative to the fixed module. The first resilient member is disposed on the first surface and movably connecting the holder with the fixed module.

Abstract: A driving mechanism is provided, including a housing, a hollow frame, a holder, and a driving assembly. The frame is fixed to the housing and has a stop surface. The holder is movably disposed in the housing for holding the optical element. The driving assembly is disposed in the housing to drive the holder and the optical element moving along the optical axis of the optical element relative to the frame. Specifically, the stop surface is parallel to the optical axis to contact the holder and restrict the holder in a limit position.

Abstract: The disclosure provides an optical driving mechanism, including a frame body, a holding member, a plate coil and a magnet. The holding member is movably disposed in the frame body and configured to hold an optical element. The plate coil is disposed on the holding member. The magnet is disposed on the frame body and corresponds to the plate coil. The plate coil acts with the magnet to generate an electromagnetic force to drive the holding member and the optical element to move along an optical axis of the optical element relative to the frame body.

Abstract: A multiple lenses driving mechanism is provided, including a frame, a first lens holder, a second lens holder, a first lens driving assembly, a second lens driving assembly and a stopper. The first and second lens holders are disposed in the frame, arranged along a longitudinal axis for respectively holding a first lens and a second lens. The first lens and the second lens define a first optical axis and a second optical axis, respectively. The first and second lens driving assemblies are disposed in the frame to drive the first lens holder and the second lens holder, respectively. The stopper is disposed between the first and second lens holders and has a first restricting surface and a second restricting surface, facing the first and second lens holders, so as to restrict the first and second lens holders in a first restricted position and a second restricted position.

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.
