Figure 3
An example of the use of a polarized image. The images on the left were taken with standard imaging. (a) shows an experiment containing clearly visible crystals and (b) their view under crossed polarizers. (c) shows a drop containing microcrystalline precipitate, while (d) shows the same drop imaged with crossed polarizers. Notice the soft glow of the precipitate and bright objects that denote larger crystals. (e) shows an amorphous precipitate; note that the corresponding cross-polarized image (f) does not show any evidence of birefringence. Each well has a diameter of 0.9 mm.
