Attaching the DIC Optical Elements
(Fig. 59)
}The attaching method is identical to that for the phase contrast optical
elements (pages 33-34), except that the positioning pin and positioning
groove should be aligned when attaching each DIC optical element.
· Align the positioning index @ on the DIC prism with the positioning in-
dex ² on a turret position and insert the DIC prism all the way into the
turret position so that the DIC prism’s frame hits the bottom of the posi-
tion and the prism’s positioning pin fits into the pin hole. When inserting,
push the spring ³ inside the turret slightly sideward.
#Be careful not to touch the DIC prism area inside the frame.
#Do not tighten the optical element centering knobs too much, for
this may deform the frame of the optical element.

Attaching the Analyzer and DIC Slider
(Figs. 60 to 62)
With the U-DICT DIC Slider
1. Remove the dummy slider from the revolving nosepiece.
2. Align the index @ of the U-ANT analyzer and the positioning groove ² of
the U-DICT DIC slider and drop the analyzer into the analyzer mount of
the DIC slider. (Fig. 60)
3. Hold the U-DICT ³ so that the side with indication faces down, insert it
into the revolving nosepiece, and tighten the clamping knob |.
With the U-DICTS/U-DICTHC/U-DICTHR DIC Slider
}The U-ANT analyzer cannot be mounted on these sliders. Use the IX2-
AN analyzer with them.
In case of simultaneous observation with reflected fluorescence
observation, the use of the IX2-AN can make the observation brighter
because it does not cause drop in the excitation light from the principles.
}It is also possible to use the IX2-MDICT DIC slider in place of the ana-
lyzer.
However, the U-MDICT3 that looks similar to the IX2-MDICT cannot be
used because the analyzer’s oscillation direction is different.
1. Hold the IX2-AN analyzer ƒ so that the side with indication faces up, and
insert the analyzer into the analyzer insertion slot … until it clicks.
2. Hold the DIC slider so that the side with indication faces down, and insert
it in the same way as the U-DICT.
