  We present an overview on the development and characterization of multiscale
laser processing optics for versatile material modifications across more than
six orders of magnitude. Starting with solutions for micromachining we present
high-NA microscope objectives creating sub-wavelength material modifications on
macroscopic scales with highest peak intensities. Moving on to the millimeter
range, the adaptability and scalability of scanning optics is examined for
large-area machining. Finally, we explore line beam optics in the meter range,
evaluating their use in uniform material processing using average powers above
100kW. This study provides an insight into the design and performance
characteristics of such optics and demonstrates their potential in advanced
laser processing.
