Dynamic Focusing Module

Multiple PSI patented technologies being applied, DFM19 is designed for dynamic focusing and 3D marking. It represents the smallest and most compact dynamic module in the industry, with outstanding features including fairly long lens travel distance(±4.5mm), fast speed, high resolution and zero drift. DFM19 offers ideal solutions for high accuracy applications, such as additive manufacturing (3D printing), laser welding and laser 3D engraving etc.
