Axial and/or radial apodizing as well as hyperresolving filters are fi
lters which may be used to produce small isolated and WS-structures in
photolithography. For the assessment of the different filters a conse
quent extension from the 3D-PSF to the 3D-line responses and the 3D-MT
F is made. Additionally the OTF and the ATF for partially coherent ill
umination are regarded. As an example the application of all of these
functions to an axial apodizer is presented.
