| Abstract: | The optical design of a semi-spherical screen fish-eye objective with field angle 180 degrees has been studied. Its application and theory of image formation have been intro-duced. The screen diameter equals 24 meters. Based on the concept of aberrational vignetting, both the skewrays can be traced so that the calculation of spot diagram has been successfully fin-ished. Firsthand information concerning image quality is shown. Finally a practical example is given. |
