OPTIONAL MODULES

# The sliding performance of the U-RSL6 or U-RSL6EM 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 than 2000 times of reciprocation, apply a thin layer of lubricant such as grease on the sliding

surface.

}This filter slider is for common 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

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 filters include an exciter filter, insert it so that the arrow inscription on the side faces down.

4. If it is required to attach a filter type inscription, write the filter type on a commercially-available round seal with diameter of

no more than 8 mm and attach the seal to the specified position.

# Be careful not to attach the seal outside the specified circular area. Otherwise, the slider may be stuck during use.

5. Insert the U-RSL6 filter slider from the right of the 6-position filter slider insertion slot on the illuminator so that inscription

"U-RSL6" comes at the deep, then attach the slider knob which has been removed in step 1 above.

Holder ring driver

a) Filter with thickness of 4 mm or more:

Place each filter so that it fits in side 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.
