Adjusting the Focus - (Fig. 15)
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 to "0". Using your left
eye only and the 10X objective, focus your specimen by
adjusting the coarse adjustment knob ①. When the
image is in view, refine the image to its sharpest focus
by turning the fine adjustment knob ②. 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.
NOTE: do not counter rotate the focusing knob as this
will cause severe problems and damage to the focusing
system.
Adjusting the Focus Stop - (Fig. 15)
Once you have adjusted the focus, turn the focus stop
③
clockwise to set your objective levels to a stop
position so they will not come into contact with your
slide.
Adjusting the Focusing Tension - (Fig. 16)
If the coarse focusing knob is very heavy when focusing
or the specimen leaves the focus plane after focusing or
the stage lowers by itself, please adjust the tension
adjustment ring ①. Located on the left side of the stand
between the coarse focusing knob and the vertical arm is
an adjustable tension control dial that is preset at our
facility. This allows the user to adjust the coarse control
tension to their individual preference.
