Paper Abstract

The aspherical surface manufacturing process improvements let suppose equivalent improvements for non-rotationnaly symmetry optical surface. For this we introduce in our optical design program such surfaces considered as very useful for some applications . We are interested in surfaces with two symmetry planes represented as a power series expressed as follow : X=Σ amn Y2m Z2n m+n ≤ 3. These surfaces can be tilted or decentered for any direction. The nine parameters used to characterize the surface, the five eccentricity parameters can be used as optimization parameters. The influences of each parameter for each ray are expressed with the exact partial derivatives according to the traditionnal CERCO method . Two exemples ares described - helmet mounted wide angle CRT display . - Off axis catoptric system for 10° field .
