F-Theta lenses enable ultra-accurate processing of flat image fields without dynamic limitations. A short-focal-length F-Theta lens facilitates short working distances, as well as very compactly-dimensioned systems. Long focal length, on the other hand, allows the processing of large image fields without external axes.
