The line scan television satellite required an optical system covering a very wide angle of 85 degrees by only 3 degrees and with equally high resolution extending out to the edge of the field. The requirement prompted a design study that resulted in the lens design described in this paper. The optical design uses the properties of concentricity of surface radii to afford a lens free from comatic and astigmatic image defects. In addition, both the spherical aberration as well as the chromatic differences of focus have been successfully suppressed below the allowable limits set for the purpose intended. The curved image surface presents no difficulty with the fiber optics bundle which can be conventiently mated to this surface. Author
