Blue Phase II of 55% CB15 (chiral dopant) in E48 (liquid crystal) observed between crossed polarizers in a 7 micrometer thick sandwich cell . The areas of different colors are regions of different orientations of the Blue Phase II "unit cells" that have a side length of around 240 nm. The picture shows the mixture during the process of slow degeneration of the Blue Phase.
Real width of the picture is about 1 x 0.7 mm.
