Standard Cholesteric Liquid Crystal Device (1 of 2)

Caption

Schematic illustration (left) and photos (right) of a standard cholesteric liquid crystal device. The green bars in the left figure are guides indicating positions with the same helix phase. Cholesteric liquid crystals reflect circularly polarized light with the same handedness as the helical structure and with wavelength fulfilling the Bragg condition (refractive index � helical pitch). In the right figure, purple light with right circular polarization is reflected.
