Efficient assembly of lens objectives using sub-cell alignment turning

Abstract

Increasing demands for single lenses and lens systems influence in particular their production technology. It has become unfeasible – both technologically as well as financially – to manually adjust lenses in pre-assembled objective lenses. In recent years, it has thus become desirable to automate many steps of the process to chain. This enables new assembly strategies that allow for tilt and air gap accuracies in the micron range and drastically reduce the time and labor of manually correcting for astigmatism and coma at the same time.
