Abstract
Until now grating machines were mainly used to produce high-resolution mechanically divided gratings by scratching the structures in thin metal layers. Hereinafter, a new method is presented to produce echelette as well as echelle gratings on curved substrate surfaces. This is achieved with a modified planing procedure whereupon there are no limits to the maximum structure height.
