Abstract :
This paper presents general closed-form expressions that allow to complement the Abbe sine condition formulation that is used for double material lens design, with additional important information about the maximum feed off-set position at the lens planar base and about the maximum scanning angle. This convenient information is absent from the Abbe formulation.. These expressions were tested for different fabricated lenses.
