Abstract
An optical system for moving a focal point along an axis employs an input telescope having a variable lens separation and a fixed field lens separated from the telescope by the sum of the focal lengths of the field lens and the second lens of the telescope. The focal spot maintains a constant size as it moves. If two input beams are used, the crossing angle of the beams remains constant.
