Switching the Filter Slider

}Hold the knob of the filter slider 1 on the illuminator and
move the knob to the left and right to select one of the three
positions, which are arranged in order of the filter pocket,
open position and shutter from the right to the left.
To adjust the observation brightness, insert an optimum ND
filter (32ND6, 32ND12, 32ND25 or 32ND50) into the filter
pocket and set the filter slider to engage it in the light path.
When not performing observation, set the filter to the shutter
position to prevent the specimen fluorescence color fading
by cutting the excitation light.
ND filter
}The ND filter can reduce the excitation light intensity to
delay color fading of the specimen. Use the ND filter as far
as this does not hinder operation.
1. Slide the filter slider 1 on the illuminator in the direction of
the arrow.
2. Drop in the ND filter 3 into the filter pocket 2.
# To prevent the ND filter from being cracked, insert it so
that the surface with indications faces the observation
side.
When replacing the ND filter, be sure to wait until the ND
filter cools down.
When the mercury burner is lit for a long period while an
ND filter is inserted, the filter and its metallic frame will
become very hot. Take care not to burn yourself.
Do not leave the filter slider to a position other than the
click positions for a long period.
}A filter other than ND filter can also be inserted provided that
the outer diameter is 32 mm and the thickness is 3 mm or
less.
# Use a reflection type ND filter (32ND6, 12, 25 or 50). Do
not use a commercially available low-reflection ND filter
as this may crack or burn the filter.
