摘要
研究K9玻璃在低压下的双折射效应,测量它的双折射率及其梯度。结果表明,当K9玻璃用作天文透镜材料时,应充分考虑其自重引起的对透镜光学性能的影响。
The birefringent effect of K9 glass has been studied under low pressure. The index of birefringence and its gradient have been measured. The consequences show that we should fully consider the influence of the self-weight resulted birefringent effect on the optical performance of lens made of K9 glass. The conclusion has practical significance to the design of astronomical lens.
