text: The mechanical tube length of an optical microscope is defined as the distance from the nosepiece opening, where the objective is mounted, to the top edge of the observation tubes where the eyepieces (oculars) are inserted.
text: The objective then projects a magnified image of the specimen which converges (is brought into focus) at the level of the eyepiece diaphragm, located ten millimeters below the top edge of the openings of the microscope observation tube--where the eyepieces are inserted (see Figures 1 and 2).
text: The image appears to be "floating" in space about 10 millimeters below the top of the observation tube (at the level of the fixed diaphragm of the eyepiece) where the eyepiece is inserted.
text: Note that this value is different from the mechanical tube length of a microscope, which is the distance between the nosepiece (where the objective is mounted) to the top edge of the observation tubes where the eyepieces (oculars) are inserted.
