Making an Optional Fluorescence Mirror Unit

} You can also fabricate original fluorescence mirror units by fitting a commercially available barrier filter, excitation filter or

dichroic mirror in the U-FF empty mirror unit frame.

Dimensions of Optical Parts

· Barrier filter

· Excitation filter

· Dichroic mirror

When disassembling and assembling the fluorescence mirror unit, place it so that the barrier filter frame

CAUTION

comes on the top (as shown above) and handle it by taking care not to stain it with fingerprints, etc.

1. Disassemble the fluorescence mirror unit by lifting up the absorption filter frame.

2. Fix the absorption filer in the absorption filter frame and the excitation filter in the main body respectively. Place each

filter by aligning the directions of the arrows located on the side surfaces toward the absorption filter frame and the main

body respectively.

Fit the holder ring driver into the groove of the holder ring driver, and fix it by rotating the filter holder ring.

} If the filter holder rings may exceed the absorption filter frame or the main body depending on the filter thickness, re-attach

the filter by placing the filter holder ring upside down.

3. Place the main body on the table as shown in the figure, and place the dichroic mirror on it gently.

4. Move the absorption filter frame gently back to the original position.
