ABSTRACT:
An energy beam machining system includes an emitter for emitting an energy beam and beam adjusting optics, such as a zoom telescope, for adjusting the pupil size of the system to multiple values. The adjusting of the pupil size can be carried out automatically, semi-automatically, or manually. In manual modes, instructions can be presented to the operator (e.g., via a monitor or pre-programmed audio instruction) indicating how to adjust pupil size. A focus lens focuses the adjusted beam directed along each path at a different focal point within a scan field encompassed in the field of view of the focus lens. Beam directing optics are configured to enable multiple scan fields within the field of view of the focus lens.
