Abstract
In the period from 1973 through 1992, Polaroid introduced six different free-form aspheric optical surfaces in some unusually innovative instant photographic cameras, made in the millions. In each case these peculiar components were used to solve unusual problems of product size, shape, and function. This presentation relates how and why those surfaces were used and how they were tooled and manufactured with high quality.
