Zeiss Universal Optical Microscope
The Zeiss Universal Optical Microscope, which operates in transmission, is used principally for studying the growth of polymer superstructures, such as spherulites. The microscope is equipped with long-working-length objectives, polarizing optics (including an insertable full wave plate), as well as differential interference contrast optics. The utility of the microscope is enhanced by a programmable hot stage (Mettler FP82 or Linkam DSC600). Data are recorded on a color CCD camera (Sony DXC-151A); transformation processes, such as crystallization or melting, can be videotaped and individual frames analyzed with a PC-based frame grabber card (Matrox Meteor) and software (Matrox Inspector).
