Abstract

An optical scan system with uniform focusing and a method are disclosed. The optical scan system comprises a working platform, a laser light source, a first scanning track, a second scanning track, a reflector, a laser scanning head, a first optical element and a second optical element. A laser beam is provided by the laser light source. The laser scanning head can be moved with right-left and front-rear by providing the first scanning track and the second scanning track. A focus point generated by the laser scanning head can be kept on a level surface by equipping the first optical element between the reflector and a scanning head, equipping the second optical element between the first optical element and the scanning head, and fine adjusting the position of the first optical element and the position of the second optical element.
