See I made a mistake in this question because I didn't remember that resistance in series in galvanometer does not affect null point, apparently. Talk about concepts needing revising.
Remember:
Resistance in series in galvanometer does not affect null point.

Galvanometer Scanner Head for Fiber Laser, CO2 Laser, and UV Laser
Galvanometer Scanner Head for marking is a new way of marking, with high precision and speed. The working principle of galvo laser marking is that the laser beam is incident on two mirrors (scanning mirrors). The reflection angle of the mirrors is controlled by a computer, and the two mirrors can be scanned along the X and Y axes respectively to realize engraving on the surface of an object to form desired shapes and patterns. Galvo laser marking is a kind of three-dimensional laser engraving technology, which can process various materials.
The galvanometer scanner laser using photoelectric sensor as feedback system is characterized by high repetition accuracy and linearity, and high cost performance. Mirror coating film selection is rich, UV, green light, optical fiber, CO2 and other coating options, strict lens quality testing to ensure the requirements of lens flatness and damage threshold, photoelectric mirror is widely used in galvo laser welding, flight marking, precision marking, precision cutting, and other industries. Key Features Of Ultra-galvo Scanner Through 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. 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 galvanometer 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 galvanometer is widely used in flight marking, precision marking, precision cutting, precision welding and other industries.
