Abstract
Method for optimizing an optical surface comprising: an initial optical surface providing step, a working optical surface defining step, during which a working optical surface is defined to be equal to the initial optical surface, a first surface cost function providing step, during which a first surface cost function of the nth derivative of the surface is provided, a set of surface cost functions providing step, during which a set of surface cost functions function of at least one criterion over evaluation zones is provided, a global surface cost function evaluation step during which a global surface cost function equal to a weighted sum of the previous cost functions is evaluated, a modifying step, during which the working surface is modified, wherein the evaluation and modifying steps are repeated so as to minimize the global surface cost function.
