【Abstract】 Some theoretical problems related to the making autofocus lens by ion-exchanging are mainly expounded. They are: the reason why the gradient distribution of refractive index can be produced) the basis for determining the ion-exchanging; the principle for select the composition of pregnent glass bar and the mathematical deduction of a parabolic model gradient refractive index.更多还原
