Paper Abstract

The design and underlying theory is given for an aspheric singlet lens capable of operating, with minimum sphero-chromatic aberration, over a range of pre-selected wavelengths. The performance of the lens is compared with a conventional aspheric (based on Fermat's principle) using finite ray tracing techniques. The use of the lens as a focusing element in a multi-wavelength high-power laser is evaluated. Finally, comments are made on its manufacture and testing and its performance compared with theoretical prediction.
