Phase Contrast - Accu-Scope EXI-310 Series Manual

Operation
(continued)
Installing the Phase Slider (Fig. 14)
(Optional)
1. Hold the phase slider ① face up (printed side
up) by the finger slots on the right side of the
slider and insert it into the slot on the illumination
column.
2. Each light ring or opening has its own position so
you need to move the slider until you hear a
"click" to ensure the ring or opening is positioned
in the center of the light path.
3. When using phase contrast for observation, fully
open the iris diaphragm adjustment lever ② to
the "O" position.
Centering the Light Annulus (Fig. 15 & 16)
The phase slider is pre-aligned at our facilities. If
realignment is necessary, follow these steps:
1. Place a specimen on the stage and bring it into
focus.
2. Replace the eyepiece in the eyepiece tube with
the centering telescope (optional).
3. Make sure the magnification of the objective in
the light path matches that of the light annulus on
the phase slider.
4. While observing through the centering telescope,
adjust its position to focus on the phase annulus
② of the objective corresponding to the light
annulus.①
5. Insert the 2mm hex wrench into the two centering
screw holes on the phase slider ③. Tighten and
loosen the centering screws until the light
annulus is superimposed on the phase annulus
of the objective.
6. Repeat the steps above to adjust centering with
other objectives and corresponding light annulus.
