Abstract
An optical device. A lens module is movably disposed in a lens housing. A drive mechanism is connected to the lens module, driving the lens module along an optical axis of the lens module. A brake mechanism is disposed between the lens housing and the lens module and moves perpendicular to the optical axis, fixing and releasing the lens module. When the brake mechanism releases the lens module, the lens module moves along the optical axis.
