蓝宝石(Al2O3)棱镜
蓝宝石因其极度的韧性和强度可以很好的应用为UV,VIS和NIR光谱波段的光学窗片材料。
蓝宝石具有多种生长方式。 Verneuil和Czochralski方法通常用于标准级蓝宝石材料。更高质量的蓝宝石,应用于电子基板。它是由Kyropulos生长制造,可以得到非常高的纯度,产品具有优良的紫外透射特性。在IR中的使用范围被限制在约5μm,并且在任何光学级别中遇到很少的困难。 它在紫外线范围内,必须注意观察,因为从140nm到240nm的透射对杂质和间隙空位非常敏感。大片蓝宝石可以通过色带生长制成。 蓝宝石具有轻微的双折射性,通常的IR窗口通常以随机的方式从晶体切割,也有对于双折射的特定应用,选择取向。 通常这是光轴与表面平面成90度,称为“零度”材料。 合成光学蓝宝石没有着色。

关于晶体切割:
Sapphire is slightly birefringent and so for critical optical or mechanical applications, the windows should be specified as 'zero degree', or 'c-cut', meaning that the optical axis of the material should be perpendicular to the plane of the window. If unspecified, the component will be of 'random' cut, but its worth noting that this is nearly always 60° to the optic axis as this is the 'softest' direction for the saw. Note that all sapphire is always single crystal, sub-grains are always avoided in the cut.
C-plane (0,0,0,1) = Z-cut
A-plane (1,1,-2,0) = Y-cut
M-Plane (1,0,-1,0) = X-cut R-Plane (1,0,-1,0)
Manufacturers seem unable to agree on the thermal expansion coefficient of sapphire, figures from 5.6 to 8.4 x 10-6 K are given. While there may be some variation due to the method of growth, and certainly due to the axis of cut, this variation is inexplicable.
