  • Closterium x400. A desmid. See previous illustration.
  • Diatom test slide x100. A variety of diatom shells are shown side by side. Microscope resolution used to be tested with such microscope slides as this. The ability to resolve the fine detail on certain types of diatoms distinguishes good microscope objectives from those of lesser quality.
