how can I make an aspherical lens?

The sphere should have a radius on 206 mm, making a lens with 90mm in
diameter, when you intersect it. (this leaves a lens thicknesson approx.
7mm).

The lens should make a focal point, 500mm away from the lens, on the image
side, cathering sylindrical, paralell light beams on the object side. (70mm
away from the lens).

Thankful for any help.

Marius
