摘要
根据布克达尔 (Buchdahl)模型得到铊玻璃自聚焦透镜的色差方程 ,计算和实验证明 :两步离子交换所得自聚焦透镜比一步交换的一级色差要大得多 .
In terms of Buchdahl model, simple equations analyzing chromatic aberrations of Selfoc lenses of Tl glass fabricated by ion-exchange technology were obtained. The equations with gradient-index chromatic constant Ψ 1(firs-degree constant) and our experiments show that the chromatic aberration by two-step ion-exchange technology is larger than that by one-step.
