Abstract
The laser marking device comprises a laser source, an optical system for projecting a laser beam emitted from the laser source to form a laser spot on an object, a light distributing element that is disposed in an optical path of the optical system and includes at least one light distributing portion that distributes a part of the laser beam to form at least one static reference line on the object so that the laser spot is formed on the static reference line, a rotating mechanism that rotates at least a part of the optical system to form a dynamic reference on the object, and a switch for selecting between a rotation mode in which the rotating mechanism is activated and a stationary mode in which said rotating mechanism is not activated.
