Abstract
The recent development of zoom lenses owes much to advanced computer techniques, such as automatic lens design, and also to techniques for precise image evaluation. It is obvious, however, that because of lens configuration and materials which have been used, the development of lens systems will find the limit sooner or later. Several attempts have been made to find ways of overcoming the limit. At present, in the case of a zoom lens, the most effective way seems to be the use of artificial crystals, especially calcium fluoride, which is quite effective in reducing chromatic aberrations. The development of a zoom lens containing calcium fluoride elements has been made possible by the achievement of a production system to synthesize large blocks of artificial calcium fluoride at moderate cost.
