What are the parts of a stereo microscope?

Stereo microscopes allow you to see opaque objects that can be directly placed on the stage of the microscope. The magnification is lower than the one of compound microscopes, but you get a stereoscopic (3D) view.

  • Stage plate: Te specimen is placed here. It should be large enough to hold the specimens that you want to look at.
  • Stage clips: The clips can be used to hold down microscopy slides. It also holds down the glass plate which covers the lamp
  • Stereo head: There are two eyepieces mounted to a stereo microscope. The stereo head holds the eyepieces and contains prisms which turn the image rightside up.
  • Eyepieces: These generally magnify the image 10x.
  • Objective(s): A conventional stereo microscopes work like binoculars and have one objective for each eye. It is possible to rotate the tube to get different magnifications.
  • Focus knob: The focus knob raises and lowers both the objectives as well as the eyepieces. This is a difference to the compound microscopes, where the stage is raised and lowered.
  • Lighting controls: Many stereo microscopes have both top and bottom illumination. The light intensity can also be controlled.
