Abstract: An optical system includes a fixed module, a movable module and a driving assembly. The movable module moves relative to the fixed module, and the movable module includes a lens unit which includes a first lens, a second lens, a first side wall and a second side wall. The first side wall has a first surface, which directly contacts the second lens, and the second side wall directly contacts the first lens. A portion of the driving assembly is directly disposed on the lens unit, configured to drive the lens unit to move along an optical axis of the first lens. The first side wall further has a second surface opposite to the first surface, and the second surface directly contacts the portion of the driving assembly. The thickness of the first side wall is different from the thickness of the second side wall.

Abstract: A lens module comprises a frame, a lens unit, and a driving module for driving the lens unit to move relative to the frame. The lens unit comprises a body made of plastic, at least one lens located in a center of the body, and an embedded member made of metal. The metal embedded member is embedded within a thinner rim portion of the lens unit by means of a plastic insert-molding process in such a manner that, at least one protrusion of the metal embedded member is exposed outside of the rim portion. When the lens unit moves relative to the frame, a location where the lens unit might touch the frame is one of the at least one protrusion, and therefore the structural strength, endure ability of impact and endure ability of friction at the rim portion of the lens unit are increased. In addition, the protrusion can also act as a positioning post or winding post for a coil of the driving module. Or, the coil can also be electrically connected to the protrusion such that the metal embedded member can transmit electric current for the coil.

Abstract: A correction method for an optical mechanism having an optical member and a fixed portion is provided, including: an external apparatus measures the angle between the optical axis of the optical member and a reference surface of the fixed portion; the result of measuring the angle between the optical axis and the reference surface is compiled into data; the data is input into a control module; the control module transmits a signal to a driving module according to the data; and the driving module drives the optical member to rotate or move relative to the fixed portion upon receiving the signal. The optical mechanism does not include a sensor to detect the angle between the optical axis and the reference surface.

Abstract: An optical system is provided and includes a fixed module, a movable module, a sensing unit and a driving assembly. The fixed module includes a base, and the movable module includes an optical member holder, configured to hold an optical member. The sensing unit is configured to obtain information related to a first rotation angle of the optical member holder when rotating around a first axis relative to the base and a second rotation angle of the optical member holder when rotating around a second axis relative to the base. The driving assembly includes a coil, the coil and the movable module are arranged along an optical axis of the optical member, and the coil is disposed around an opening of the base. The first axis or the second axis is perpendicular to the optical axis.
