Design Challenges for the 1990's

Abstract

The past decade has featured some dramatic advances in areas touching on lens design. These include new levels of ease and accuracy in aspheric fabrication, a better appreciation of cost/weight/package size/performance tradeoff issues, an amazing increase in computing speed, better cost, accesibility. user-friendliness, and nascient signs of computer intelligence. Impressive as these advances are. we are ultimately forced to realize that there is no replacement in the near term for good old human thinking.
