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.
