Abstract

It is sometimes necessary to go back to basics when too many lens design requirements are suspected of drastically reducing the potential solution set. Results from a study of a family of plastic-glass triplets that have to be temperature compensated as well as optically corrected, reveal the limited number of promising solutions. At this point, logical decisions can be made to increase the set of potential solutions. This culminated in the design for the lens used in Kodak's "EKTRAMAX" Camera. The design is compared with several all glass solutions, and justification for using an asphere is discussed.
