2) Use the slide holder to gently secure the slide.
3) Turn the X and Y stage moving knobs to position the specimen in the center of
viewing field.
Caution:
Be sure not to allow an objective to touch a specimen slide when changing
objectives.
3.3 Focusing
1) With the 10X objective in position, raise the
mechanical stage using the coarse focus knob
until the specimen is close to the objective.
2) Turn the condenser top lens into light path.
3) Turn the coarse focus knob until the specimen
is in focus.
4) Use the fine focus knob to obtain a sharp
image.
5) Turn the condenser focus knob (
Fig. 5
) to
raise or lower the condenser till the image of
field is focused.
6) Turn the condenser centering screws (
Fig. 5
) to move the image of the field into the
center of the viewing field.
7) To get a good focused image, you may need to combine the focus knob adjustment
and interpupillary distance adjustment, along with eyepiece diopter adjustment
