Abstract

A procedure is described wherein a common method for locating good starting points to the Cooke design is adapted to the problem of the reflective triplet. The procedure begins with a determination of some physical and first-order criteria. This criteria is employed to produce a binary function which expresses the acceptable areas of solution space. Candidate systems in their all-spherical element form are then considered for their relative departure from aplanatisism. A three-dimensional topography is produced from the physical criteria's binary data and the design's third-order error content. Selected points on the topography are investigated for their relative levels of aberration. The added freedom of general conic deformity is then permitted to determine the design's potential as an aplanatic, flat-field anastigmat.
