藍(lán)寶石Al2O3 因其極度的韌性和強(qiáng)度可以很好的應(yīng)用為UV,VIS和NIR光譜波段的光學(xué)窗片材料。
藍(lán)寶石具有多種生長(zhǎng)方式。 Verneuil和Czochralski方法通常用于標(biāo)準(zhǔn)級(jí)藍(lán)寶石材料。 更高質(zhì)量的藍(lán)寶石,應(yīng)用于電子基板的由Kyropulos生長(zhǎng)制造,這可以得到非常高的純度,具有優(yōu)良的紫外透射特性。 在IR中的使用范圍被限制在約5μm,并且在任何光學(xué)級(jí)別中遇到很少的困難。 它在紫外線范圍內(nèi),必須注意觀察,因?yàn)閺?40nm到240nm的透射對(duì)雜質(zhì)和間隙空位非常敏感。大片藍(lán)寶石可以通過(guò)色帶生長(zhǎng)制成。 藍(lán)寶石具有輕微的雙折射性,通常的IR窗口通常以隨機(jī)的方式從晶體切割,也有對(duì)于雙折射的特定應(yīng)用,選擇取向。 通常這是光軸與表面平面成90度,稱為“零度"材料。 合成光學(xué)藍(lán)寶石沒(méi)有著色。

關(guān)于晶體切割:
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.Al2O3 圓形藍(lán)寶石窗片 Al2O3 圓形藍(lán)寶石窗片
