desired observation method.

Effects of Dummy Slider

The dummy slider ² has been installed on the revolving nosepiece at the

factory. It can be replaced by loosening the clamping knob ³ when a DIC

prism is to be used. However, in observations other than DIC, be sure to

push in the dummy slider in order to prevent flare.

Centering the Field Iris Diaphragm (FS)

1. Slide the mirror selector lever @ to "BF".

2. Engage the 10X objective by rotating the revolving nosepiece, place the

specimen on the stage and adjust approximate focusing.

3. Pull out the FS knob ² on the reflected light illuminator to reduce the

aperture iris stop a little.

4. Rotate the two FS centering screws ³ using the Allen screwdriver to ad-

just so that the field iris image becomes concentric with the field of view.

5. While pushing in the FS knob ², open the field iris diaphragm until the

field iris image inscribes the field of view. If the image is found to be

eccentric, adjust the centering again.
