This paper touches upon the features and limitations of shaping techniques and promising application ranges of high-aperture diffraction optical elements. A number of applications require manufacturing ruled high-aperture diffraction optical elements on spherical and aspherical surfaces with a large sag, which is unachievable in practice with the existing manufacturing equipment. Engineering solutions have been suggested that open up the possibility to broaden the range of high-aperture diffraction optical elements basing on the use of pendulum-type ruling engines with subsequent replication of diffraction structure in the polymer layer.
