【摘要】 对梯度折射率(GRIN)棒透镜色差的影响因素进行了研究,在玻璃光学性质计算模型的基础上建立了梯度折射率棒透镜色差估计函数与基础玻璃性能、交换离子对性质和参与交换的离子数量之间的关系。对Na+/Li+,K+/Cs+和K+/Tl+交换制备的梯度折射率棒透镜的色差进行了计算,结果表明,GRIN棒透镜的色差评价函数主要取决于基础玻璃和交换离子的性质,而与参与交换的离子数量无关。更多还原

【Abstract】 Contributing factors to chromatic aberration of gradient index (GRIN) rod lens is investigated. Based on optical glass properties calculating model, dependence of chromatic aberration evaluating function on base glass properties, nature of exchanging ionpair, and the quantity of ion exchanging was established. Calculation on chromatic aberration of GRIN rod lens prepared by Na+/Li+,K+/Cs+ and K+/Ti+ exchanging was performed. The result shows that the function value mainly depends on base glass properties and nature of exchanging ionpair, and hardly depends on the quantity of ion exchanging.更多还原
