Microscope head application:
The head portion or body tube of microscope connects the eyepiece to the objective lenses.
If you were to open the body of the microscope you would find a mirror or prism depending on the type and quality of the microscope. The prism or mirror is used to reflect the light and reorient the image by making it appear right side up.
In compound microscopes with two eye pieces there are prisms contained in the body that will also split the beam of light to enable you to view the image through both eye pieces.
