Abstract

Two new families of zoom optical systems, developed for industrial and medical laser applications, are introduced. First we discuss the main physical processes involved in industrial laser applications and the requirements for the optics. The spatial beam parameters are reviewed, explaining the relatively new concepts of intrinsic stigmatism and intrinsic astigmatism. Then two new zoom systems are discussed, including experimental examples: VariSpot^(R), which delivers round spots with adjustable diameters at fixed working distances, and VariFoc^TM, able to adjust spot shapes and sizes at different working distances. We conclude that these systems represent a valuable addition for industrial and medical lasers.
