Under non-sequential mode, you may use <W`#gn0b6
RP2_l$
Toroidal Lens which support aspheric surface (faK+z,*6R
rUlS'L;$"
or you may use Biconic Lens if you make use of conic constant alone to create aspheric surface. X*g(q0N<S
Q|,B*b
Hope this would help, bu tbear in mind that diffraction effect is not modelable in non-sequential mode.
