1
Check that the phase ring and the objective match, and that
both are steadily set on a click stop.
2
Use the CT to focus the condenser phase ring (bright) (1) and
the objective phase ring (dark) (2) image. If the bright phase
ring’s image is not sharp, adjust the CT head until you can see
a clear image of the phase ring. (Fig. 37)
3
Adjust the bolts of the two centering holes in the phase
contrast slider using a screwdriver until the bright ring and
the dark ring match. (Fig. 38)
4
The 4x and the 10X phase contrast objectives use the same
ring on the phase contrast slider. The coincidence of the
phase ring center and the phase contrast center must be
verified with both objectives. (Fig. 39)
If the phase ring is incorrectly centered, the contrast will be
severely impaired.
The phase ring may need recentering during and after
observation of very thick specimens.
The phase ring may show an apparent misalignment if the
specimen is not flat.
