Operation
(continued)
Adjusting the Focus
To ensure that you obtain sharp images with both eyes,
(since eyes vary, especially for those wearing glasses) any
eyesight variation can be corrected in the following
manner. Set both diopter collars
②
to “0”. Using your left
eye only and the 10X objective, focus your specimen by
adjusting the coarse adjustment knob. When the image is
in view, refine the image to its sharpest focus by turning
the fine adjustment knob. Rotate the diopter collar to
obtain the sharpest focus. To obtain the same sharp
image using your right eye, do not touch the coarse or fine
adjustments. Instead, rotate the right diopter collar until
the sharpest image appears. Repeat several times to
check.
IMPORTANT: do not counter rotate the focusing knobs as
this will cause severe problems and damage to the
focusing system.
Focusing on a Specimen
To adjust focus, rotate the focus knobs on the right or left
sides of the microscope to move the objective up and
down. Coarse focus ① and fine focus ② knobs are
identified in the figure to the right.
The figure to the right illustrates the relationship between
the rotational direction of the focus knobs and the vertical
motion of the objective.
Focus travel: The default focus travel from the surface of
the plain stage is up 7mm and down 1.5mm. The limit can
be increased up to 18.5mm by adjusting the limit screw.
