  Simple Pocket Microscope

  The simple pocket microscope is made from brass. The lens on the underside of the microscope is a Stanhope lens. The ocular lens is a lower-power convex simple lens. Each lens can be focused by drawing the body tube in and out of the drawtube. The mirror is located between the lenses and revolves to reflect light into either lens. To view, specimens are held on a pin, between tweezers, or between the microscopist's fingers as the small size cannot accommodate slides. The lower simple lens can be removed so the instrument can be used as a magnifier.
