[OM] Wasserman-wolf problem solved by graduate student--should be helpful to lens designers.

[Mike Gordon via olympus]

 A direct numerical solution for aspherics to  correct spherical aberration in 
lens design has been a vexing problem.       Often now can use  a pair of 
aspherics with a brute force approach to correct much of it but the calibration 
of such lenses depend on imprecise calculation. A Ph.D. student in 
nanotechnology came up with an idea for the solution for this almost mythical 
problem  while eating bread with Nutella. Less than a day later, the program 
confirmed an exact solution.

It should certainly have some simplifying effects on lens design.  

Nutella added to grocery list, Mike
