Principle Of 3D Dynamic Focus Laser Marking Machine
Feb 24, 2018

The use of high-energy-density laser on the workpiece local irradiation, the surface material vaporization or color change chemical reaction, leaving a permanent mark.

Laser marking can mark a variety of text, symbols and patterns, the size of the characters can even reach the micron level. The laser beam for laser marking is generated by the laser. After a series of optical conduction and processing, the laser beam is finally focused by the optical lens, and the focused high-energy beam is deflected to the designated position on the surface of the object to be processed to form a hollow trace.

Traditional 2D laser marking is used after the focus mode, generally only within the specified range of plane marking. 

The advent of the new 3D laser marking machine to solve the 2D laser marking machine has long been an inherent defect, 3D laser marking machine using advanced pre-aggregation, more dynamic focus base, which takes light theory, like Candle imaging works by software control and moving the dynamic focusing mirror, the laser beam is focused on before the variable expansion beam, in order to change the focal length of the laser beam to achieve different objects on the level of accurate surface focusing processing.
