Mirror galvanometers, also known as laser engravers or laser cutters, are a series mirrors that move fast to change the laser's path. A rotation of just 10 degrees at the top of the head will produce 1 1/4 inches of movement at 10 inch. It can also serve to trace laser paths before cutting or engraving.
MCWlaser PRO can be described as a split-type laser machine. This means that both the laser source, and the engraving machine are in separate modules.
