In 1892, Biot confirmed that the colors on propagating white light parallel to the optical axis of a quartz crystal placed between crossed polarizers arise from two distinct effects, the rotation of the plane of polarization of monochromatic light and dispersion of the rotation with respect to wavelength. Biot s discovery was extended to the optical rotation of natural products in solution or in the liquid phase, and this is of chemical significance, as it indicates that rotation is a molecular effect. 

Figure 2.3 shows an optical micrograph obtained with reflected fluorescent light. This technique clearly shows the presence of a multiple, O/W/O/W, emulsion which would have been extremely difficult to detect by other means. Combined techniques can be used to observe different dispersed species. For example, reflected white light can make dispersed particles easy to observe (Figure 2.4a) whereas reflected light on...
