2.4 Adjusting Interpupillary Distance
The Interpupillary Distance is essentially the distance
between your two pupils expressed in millimeters. When
set correctly, one will see one uniform round field of
view or FOV. The adjustment is made by simply pulling
apart or pushing together the eyetubes until a uniform round field is achieved.
Make note of the number marked on the viewing head so
you can repeat the setting later. The number indicated on
the microscope head is your IP expressed in millimeters.
That number will also need to be dialed up on the left
eyetube as shown at right.
Once this is done, the microscope is adjusted to this user. Other users will have
different IP’s and different focusing abilities so re-adjustment is necessary.
