I usually use Binary1 Surface to model DOEs (Kinoforms) in sequential mode.
The Binary Surface can be shaped rotational symmetric (Sphere or Asphere) but this kind of Elements are usually produced on a Foil that only allows bending it in one dimension (Cylindrical).
The (extended) toroidal grating surfaces allow this shape, but are only supporting linear gratings.
Have I overseen a surface type?
Is there a possibility to bend a Binary1 into a cylinder?
