Abstract
Some technical issues in the design, fabrication and evaluation process of the photographic objective lens are treated. In the design process, a unique design technique called the quasi-equivalent glass method is applied. Also, a convenient method is described for the determination of tolerances of the refractive index profile. Performance evaluation showed that the GRIN material made by sol-gel method is usable for photographic lenses.
