ABSTRACT:
An optical system is adapted to conjugate an object plane with an image spherical dome whose radius is less than its focal length and whose exit dioptric is a spherical dome on which the image spherical dome is substantially superimposed. The optical system can be used in an exposure device for modifying by physical-chemical treatment the power profile of an artificial optical lens made from a photopolymerizable material. The device comprises a source of radiation and between the source of radiation and the artificial optical lens to be irradiated a mask adapted to modulate the energy flux spatially. The exposure device comprises a curved field lens system formed by the optical system.
