Patent attributes
A laser material processing system comprises: a housing defining an engraving chamber, an xy laser beam steering system, a non-telescoping focus mechanism, and a camera system that facilitates production of engravings that exceed the xy dimensions of the engraving chamber. The housing includes a removable bottom panel that allows processing of workpieces that exceed dimensions of the engraving chamber. The focus mechanism includes a carriage mirror subassembly, a sliding member moveably attached to the carriage mirror subassembly, and a focusing lens subassembly attached perpendicularly to a lower portion of the sliding member. The carriage mirror subassembly and focusing lens subassembly are configured to receive and focus a laser beam to a focal point. The focusing lens subassembly is adjusted along a z-axis by disengaging the locking component and vertically sliding the sliding member and is locked into a position by engaging the locking component with the sliding member.
