摘要： Adjustable-focus laser cleaning galvanometers, cleaning systems, and cleaning methods in the field of laser cleaning are disclosed. According to aspects herein, an adjustable-focus laser cleaning galvanometer includes a body, a laser, an adjustable lens set and a galvanometer. The adjustable lens set and the laser may be mounted on the body. In some implementations, the adjustable lens set may be configured to convert or transform a laser beam emitted from the laser into a focused beam and adjust the focal length of the beam. Further, the galvanometer may be mounted on the body and can rotate or swing on the body.
