A 3048-mm,f/2.5, flat-field Schmidt telescope design.
To test the LASL lens design program's capabilities with aspherical surfaces, a conventional Schmidt telescope was analyzed and compared with a newly designed flat-field Schmidt design. The remarkable imaging qualities of the conventional design were demonstrated. Introducing a field-flattener lens near the focal surface of the curved field design resulted in increased chromatic defects and appreciable resolution loss. The LASL program makes a statistical analysis of the traced skew rays generating geometrical image spots.
