Automatic Optimization of IR Fish-eye Lenses

The technical difficulties in the automadc optindzation of IR fish-eye lenses are overcome and the mid-IR. and far-IR fish-eye lenses were designed. In the automatic optimizations of those lenses the Aitkin interpolation is applied to remove the tmubles caused by total reflection or no intersection of rays. The complex optimization speeds up the optical automatic design, and the artifi- cial expansions of the stop coma and barrel distortion improve the illuminance distribution on the image planes. The artificial expansions of the aberrations are achieved automaticaly by guiding iteration calculation. Facts have proved that the designed IR fish-eye lenses have high qualities.
