Focusing Units

These assemblies focus the parallel beam from the collimating unit onto the workpiece. The size of the focused spot and the depth of focus are given by the combination of collimating optics, focusing optics and beam quality. The focusing units come either with a fixed or a z-adjustable focus position. For the z-adjustable unit the focal point position can be manually adjusted.
