Desktop Fiber Laser Marking Machine

High Precision Field Lens

The field mirror focuses the collimated laser beam at one point, improves the energy density of the laser beam, uses the high energy of the laser to process various materials such as cutting, marking, welding, cleaning and surface treatment. At the same time, when the direction of the incident laser beam changes, the field mirror can still maintain the spot with the same relative size and energy density, so that the laser beam can be used for different materials The point of position is processed. The combination of field mirror and galvanometer which can change the direction of laser beam quickly and accurately can realize the high-speed and precise processing of materials.

The function of laser field mirror

First, focus the collimated laser beam on the focus of smaller area, improve the energy density of laser beam, and improve the ability and efficiency of laser processing.

Second, the change of laser beam direction by galvanometer is converted into the change of focus on the position of processing material, so as to realize high-speed and precise laser processing.
