Right-/Left-hand Operation
The coaxial pinion can be attached to either
side of the stage (also see 6. Assembly, p. 16
onwards). To change the side, follow these
steps:
• Loosen the lock screw (37.5) at the bottom
left-hand side of the stage; the necessary tool
is attached to the bottom of the stage on the
right-hand side
Caution:
The condenser must be lowered!
• Slide the stage all the way back
• Release the screw (37.6) on the coaxial pinion
and pull the pinion out
• Place the flat fine focus wheel (37.3) on the
side to which you intend to mount the coaxial
pinion; the wheel is held in place
magnetically; ensure that the button snaps
into place. Attach the other focus knob on the
opposite side
• Fasten the coaxial pinion to the other side of
the stage by retightening the appropriate
screw.
• Return the stage to the starting position and
retighten the lock screw; after installation of
the stage control, move object guide all the
way to the left side of the instrument; keep
turning when guide has reached the end of
travel until a click noise is heard
• Readjust the condenser
8.3 Focusing
Coarse and Fine Focusing
Coarse and fine focusing wheels are located on
either side of the stand (fig. 37 and 39).
The special form of the flat fine focus wheel
(37.3) lets users enclose the coaxial pinion in
their hands while operating the fine focus with
one finger. The flat wheel should therefore be
mounted onto the appropriate side.
See right-/left-hand operation of the stage.
Height Adjustment of the Focusing Wheels
• Defocus the image by moving the stage down
with a full turn of the coarse focus wheel
(37.2, 39.1)
• Grasp the right-hand and left-hand focus
knobs at the same time and press the knobs
gently upward or downward into the desired
position
• Refocus the image
