Key Features of Ultra-Galvo Scanner


  • Through kinematics and dynamics simulation, the mirror with certain inertia is matched for each galvo meter.  Moreover, the rotor of the galvanometer has been optimized and has excellent dynamic properties and response characteristics.  


  • In addition, high precision miniature bearing axial preloads ensure high rigidity and low friction operation, and special attention is paid to bearing life.  


  • Photoelectric galvanometer is a kind of galvo meter which uses photoelectric sensor as feedback system. It is characterized by high repetition accuracy and linearity, and high cost performance.  


  • Galvanometer scanning mirror is available for common laser wavelengths and energy levels. Moreover, all the mirrors are optimized to take into account the inertial load, rigidity and flatness of the lenses.  


  • Photoelectric galvo meter is widely used in flight marking, precision marking, precision cutting, precision welding, and other industries.
