Its 23-bit resolution delivers excellent positioning and repeated-positioning accuracy, with position monitoring and feedback of the galvanometer and real-time status detection. Because installing the grating needs more space, the encoder section at the base of the unit sits higher than on a photoelectric analog galvanometer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eThe single-axis galvanometer consists of a galvanometer part based on moving magnet technology and a high precision sensor as a feedback part.\u003c\/li\u003e\n\u003cli\u003eThrough kinematics and dynamics simulation, the mirror with certain inertia is matched for each galvanometer. Moreover, the rotor of the galvanometer has been optimized and has excellent dynamic properties and response characteristics.\u003c\/li\u003e\n\u003cli\u003eGrating galvanometer is a kind of galvanometer with grating encoder as feedback system.
