低热光常数火石玻璃熔制工艺的探讨

The Melting Technology Inquiry for "Athermalized" Flint Glass

不均匀温度埸下使用的光学仪器,为了消除由温度梯度引起的热畸变,必须采用低热光学常数玻璃。为此,我们研制定型了低热光常数火石玻璃。本文报导研制过程和熔制工艺。

In order to eliminate thermal distortions caused by temperature gradient, "athermalized" glass must be used in optical instrumenst applied in inhomogeneous temperature field. So we developed and fixed a "athermalized" flint glass.
