Illustration Procedure
2. Focusing
When the microscope unit does not well focus and
the slit image is not clear
(with magnification drum unit at 16×):
Remove the eyepiece unit.
Place the diopter telescope and sight a target as
far as possible to check for diopter zero setting.
The “0” on the diopter adjusting ring should be
at the zero marker with 0.5 diopter allowance.
If not, correct it.
Put into or put out the image lens frame (44670
1501) so that the finest focus is obtained at the
“0” diopter on the scale.
After adjustment, apply the screw lock.
Mount the eyepiece unit on the magnification
unit.
Turn the magnification unit clamp knob clock-
wise to couple the eyepiece unit with the magni-
fication unit, and then set the magnification
drum at 25.6×. Focus each unit by moving the
magnification lens frame (44670 1016) forward
and backward.
Apply the screw lock after focusing.
