FOCUSING
The eyepieces can be focused by placing the focusing rod in the hole where the lamp and microscope arms rotate.
With the focusing rod in place, adjust
the beam width to give a narrow
parallelepiped. The beam should be in
center of your field of view. If it is
not check the lever on the side of the
light tower which changes the lateral
angle of the light source to see that it
is in the click position. Looking
through the eyepieces (one at a time)
rotate the eyepiece counter-clockwise
until the beam is blurred then clockwise
until it just comes into focus.
Remove the focusing rod and you are
ready to examine the patient.
