Focusing Controls, see figure 3
1)
Focusing adjustment
is accomplished by using the large coarse
adjustment knobs located comfortably on each side of the frame. Fine
adjustment is accomplished using the smaller knobs located on the
same focus shaft. This coaxial arrangement allows for easy, precise
adjustment without drift or discomfort.
2)
Focus Control
Turning either of the coarse focus control knobs will
raise or lower the stage. The smallest graduation on the fine adjust
knob index scale is 2
μ
m of vertical.
3)
Focus Tension Adjustment
The tension of the coarse focus is
adjustable and preset at the factory for ease of use. If you wish to adjust
the coarse focus tension, first locate the tension adjustment ring.
Turning the ring toward the front of the microscope increases the
tension, and toward the rear of the microscope loosens it. Tension is too
high if you experience physical discomfort.
4)
Pre-focusing or Focus Stop Control.
Use of this feature will insure
that the short working distance objectives don’t contact the stage or
slide glass when using the microscope. Its use also simplifies focusing.
After focusing on the slide glass with the coarse adjustment, rotation of
the lever toward the rear of the microscope will set an upper limit on
the coarse adjustment movement. After changing slide glass or
objectives, focusing is easily accomplished by rotating the coarse
adjustment knob to reach the pre-focused position, then making fine
adjustments with the fine adjustment knob. Focusing movement with
the fine adjustment isn’t affected by using the pre-focusing lever.
