Abstract
This application discloses an apparatus for minimizing the optical effects of transmissive domes, and for using the dome surfaces to correct for other optical aberrations and distortions. Herein, the inner surface of the dome is designed to correct for unwanted optical effects of the outer surface of the dome and may also be used to correct for other anticipated effects in the overall optical system.
