观察到了可见光和近紫外光在蓝相液晶中的布拉格衍射。发现有两个不同的蓝相：一个是稳定的，从约0.5 ℃以下的清亮点以下约0.2 ℃以下，并具有体心立方或简单立方结构。第二个明显不同的阶段出现在0.2 ℃范围内，紧接着低于清亮点。这个阶段的性质目前尚不清楚。
Bragg diffraction of visible and near-ultraviolet light in the blue phase of a cholesteric liquid crystal have been observed. It is found that there are two distinct blue phases: One is stable from about 0.5 C below the clearing point to about 0.2 C below it and has either a body-centered-cubic or simple-cubic structure. A second, clearly distinct phase appears in the 0.2 C range immediately below the clearing point. The nature of this phase is unclear at this time.
