This paper discussed the scheme of modeling compound aspheric components during the optimization process. First, the method to model the refractive index and thickness changes of the resin layer induced in the injection-mold process is described. It demonstrated the available constraints upon the refractive index difference between the resin and the glass during the optimization run. The tolerance aspects of such components are then investigated, including the refractive index and thickness of the resin layer, as well as the conventional surface roughness, element position and rotation errors, and surface slope errors; especially for the centering tolerance. It is shown that the approximate model might be useful for different combinations with UV-curable resins and glasses for aspheric lens design and fabrication. An objective for optical pickup system comprising one compound aspheric surface is designed with the scheme.
