Hudson NH — Nutfield Technology ( the leader in galvanometer laser scanner manufacturing notes that with the increasing proliferation of lasers, laser technology and new materials, there is an increased need for laser beam positioning options.  One of the more exiting positioning architecture technologies is the introduction of 3-axis scan heads.

With a post-objective3-axis scan head, the beam enters an expander lens where it diverges rapidly until it enters an objective lens. The beam then converges and passes through, and is steered by, a set of X and Y mirrors, which are galvanometer mirrors.

Post-objective 3-axis scan heads offer designers the speed advantages over a 2-axis system. They can also provide a small spot size and the ability to scan large field sizes like an X, Y plotter. A post-object laser scanner architecture has a two-dimensional x-y scanning mechanism that's placed after a movable expander lens and a focusing objective lens. These scan heads are also very good at operating in three dimensions. Because of these attributes, the 3-axis scan head is ideal for cutting, marking, rapid prototyping, drilling, and imaging on contoured surfaces. They work well on photosensitive plates, wood, textiles, tiles, metals, paper and stone.
