Mounting the Coaxial Fluorescence
6
Illuminator
1. Using the Allen screwdriver, loosen the illuminator clamping screw @.
2. Fit the round dovetail ² at the bottom of the illuminator into the mount
dovetail ³ on the microscope body, and tighten the clamping screw @.
}To prevent the microscope from turning over after the illuminator is
installed, the rotation angle should be limited to within ±60° from the
rear direction.

Mounting the ND Filter
}Color fading of specimen can be delayed by attenuating the excitation
light intensity using an ND filter. Use the ND filters as far as they do not
hinder observation.
}When it is difficult to mount the ND filter, detach the knob on the slider
and remove the slider. Then try to mount the ND filter again.
1. Slide out the filter slider @ of the coaxial fluorescence illuminator so that
the filter pocket ² is visible.
2. Insert the ND filter ³ in the filter pocket ², and insert it so that the notch
of the filter push ring | comes on the bottom side.
}When the filter is thick (i.e. 5 mm or more), the filter will not lay down so it
is not necessary to use the push ring |.
3. Apply the filter push ring | against the filter so that it will not lay down.
4. Drop the light leak prevention cap ƒ into the filter slider.
# Even when no filter is used, the filter push ring | should be
mounted and the light leak prevention cap ƒ should be dropped
in to prevent light leak.
# Insert the filter so that the side with the indication faces the
observing side. Otherwise, the filter may crack due to heat.
# Before replacing the filter, ensure that it is cooled down.
When the mercury burner has been turned on for an extended
period, the filter and its metallic parts get very hot. Be careful not to
burn yourself. Also do not leave the filter slider knob in a position
other than the click stop positions.
}A filter other than the ND filter can also be mounted provided that its
diameter is no more than
mm.
# Always use reflection type ND filters (32ND6, 12, 25, 50). If an
absorption-type 32LND filter series or a commercially available
ND filter is used, the filter crack or burn may result.
32 mm and the thickness is no more than 6
