To distinguish polymer crystals from amorphous regions, we use a special property of the crystals alluded to before—birefringence. We image by passing the incoming light through one polarizer and then passing the transmitted light through a polarizer that is “crossed” or polarized at a 90° with respect to the
NettetThe illustrations in Figure 8 present the crystal as it will appear in the eyepieces of a microscope under crossed-polarized illumination as it is rotated around the microscope optical axis. In each frame of Figure 8, the axis of the microscope polarizer is indicated by the capital letter P and is oriented in an East-West (horizontal) direction.
NettetPolarized light microscopy is used extensively in optical mineralogy. Although the invention of the polarizing microscope is typically attributed to David Brewster around 1815, Brewster clearly acknowledges the priority of Henry Fox Talbot, who published his work in 1834.
