6-Position Filter Slider U-RSL6
}This filter slider is for use with the BX-URA2 or BX-RFA illuminator and accommodates a total of six excitation and ND
filters. It is designed to prevent centering deviation between the optical axes of the excitation filters when multiple
excitation mirror units are used and switched.
Filter Mounting Procedure
Slider knob
1. Remove the slider knob on the opposite end to the extremity where the slider inscription is engraved, and place the filter
slider so that the surface with the slider inscription faces down.
2. Remove the filter holder rings from the filter insertion positions by turning it counterclockwise using the provided holder
ring driver.
# The insertion orientation of the holder rings should be changed according to the thickness of the mounted filters.
3. If the mounted filter includes an exciter filter, insert it so that the arrow inscription on the side faces down.
a) Filter with thickness of 4 mm or more:
Place each filter so that it fits inside the holder ring.
b) Filter with thickness of 4 mm or less:
Place each filter so that it does not fit inside the holder ring.
If you perform transmitted light observation or you do not want to use a filter,
mount the provided light shield plates (having the same size as the filter) in
place.
If nothing is mounted, the scattered light of reflected lighting may enter your
eyes or the view in transmitted light observations will be deteriorated.
4. If it is required to attach a filter type inscription, attach a seal as described in the next section on the U-RSL6EM filter slider.
5. Insert the filter slider from the right of the 6-position filter slider inlet slot on the illuminator so that inscription “U-RSL6”
comes at the deep, then attach the slider knob which has been removed in the above.

# The sliding performance of the U-RSL6 or U-RSL6RM filter slider may drop when it has been used for 2000 or
more times of reciprocation. In this case, remove the dirt and contamination on the sliding surface. If it is expected
to use the slider for more 2000 times of reciprocation or more, apply a thin layer of lubricant, such as grease on
the sliding surface.
