A method for evaluating the thermal dimensional stability and homogeneity of beryllium mirrors is described. Thermal dimensional instabilities are shown to be highly dependent on crystalline anisotropy. An x-ray quality control technique is discussed which can be used to predict optical performance under changes in ambient temperature.
描述了一种评估铍镜热尺寸稳定性和均匀性的方法。热尺寸不稳定性被证明高度依赖于晶体各向异性。讨论了一种X射线质量控制技术，该技术可用于预测环境温度变化下的光学性能。
