Engaging and Disengaging the
3
Zooming Knob Click Stop Position
}When the click stop knob is engaged to ON, the click stop function is
engaged for each zoom ratio indicated with the zooming knob. When
the knob is disengaged to OFF, the zoom magnification can be varied
continuously and finely near the click groove.
}Click stop can be provided for the nine zoom ratios from 0.8 to 5. The
click stop is engaged when the microscope leaves the factory.
1. To disengage the click stop function, rotate the click stop ON-OFF screw
@ counterclockwise (by about two turns from the ON position, in the
direction opposite to the arrow) using the Allen screwdriver.
# Do not rotate too much, or the cover may be damaged.
2. To engage the click stop function, rotate the click stop ON-OFF screw @
fully clockwise (in the direction of the arrow) using the Allen screwdriver.
The zooming knob then stops at every position corresponding to the
zoom ratio indicated on the zoom ratio indicator ².

Adjusting the Aperture Iris Diaphragm
}Adjusting the aperture iris diaphragm improves the insufficiency of
brightness in the peripheral section light at intermediate zoom ratios
as well as the depth of focus.
However, setting the aperture iris diaphragm too narrowly degrades
resolution.
When performing fluorescent light observation, it is recommended to
open the aperture iris diaphragm fully for bright observation.
1. Adjust the aperture iris diaphragm knob @ to the left or right.
Rotating the ring toward the left "¦" opens the aperture; rotating it toward
the right "
confirm the contrast and focal depth improvement effects.
# Do not close the aperture too much, for this may cause degradation in
resolution and/or insufficiency of brightness in the peripheral section.

Using the Objective Correction Collar
}The MVPLAPO 2XC objective is equipped with a correction collar @,
which corrects the aberration produced by a medium such as water or
plastic container.
When observing the specimen through a liquid or petri dish cover, rotate
the correction collar to find the position that provides the best contrast,
· Correction is possible for aberrations equivalent to a water depth of about
5 mm.
· The effect of the correction collar may be less sensible when the zoom
ratio is low or the aperture iris diaphragm is stopped down.
}When the MVX-2RE revolving nosepiece is used, hold the objective so
that the revolving nosepiece does not displace from the position when
turning the correction collar @.
