Abstract: A lens driving device and a driving method thereof are provided. The lens driving device includes a lens frame, a magnetic group, a driving element group and a control device. The lens frame carries at least one optical element. The magnetic group includes a plurality of pairs of magnetic elements. The driving element group includes at least two coils. The control device supplies power to the driving element group so that the lens frame is driven by the driving element group to move. The driving element group is disposed on the lens frame, and the amount of the lens frame is equal to that of the driving element group. The control device in a first driving state supplies the power to the coils in sequence so that the driving element group is moved from a pair of magnetic elements to another pair of magnetic elements.

Abstract: A sight includes a main body, an erecting unit and a compensating mechanism. The compensating mechanism includes a fixing unit, a cover and an switching unit. A compensating mechanism for a sight includes a base unit, a transmission unit, an adjusting cap, a movable unit and a lock unit. The adjusting cap is located in a first position when the adjusting cap is locked by the lock unit. The adjusting cap in the first position can be rotated in a second direction or in a third direction opposite to the second direction when the lock unit is moved in a first direction to release the adjusting cap. The adjusting cap stops in a second position when the adjusting cap is rotated in the third direction so that the movable unit is propped against an end of a groove of the adjusting cap.

Abstract: A lens assembly includes a lens unit and a first reflective element. The lens unit includes a plurality of lenses and the back focal length of the lens unit is longer than the total length of the lens unit. The first reflective element includes a first surface, a first prism surface, and a bottom surface, and the first prism surface connects the first surface and the bottom surface, respectively. The lens unit and the first reflective element are arranged in order from an object side along a first axis. A light from the object side enters the first reflective element from the first surface and then guided to the first prism surface.
