Setting DIC
•
Open the aperture diaphragm on the condenser completely. Put on the specimen.
•
On the nosepiece, rotate in the objective suitable for DIC.
•
Put the corresponding DIC slider (Fig. 4-8/
3
) into the slot on the nosepiece. Make sure the DIC slider
snaps safely into position.
•
On the condenser, (Fig. 4-8/
1
) rotate the proper DIC I, II or III condenser module (as identified by the
stickers on the front of the condenser) into the light path.
•
Put the three-position contrast slider (Fig. 4-8/
2
) with the analyzer position into the stand or rotate in
the D P&C analyzer module on the reflector turret. Watch for the correct locking position.
•
Adjust optimum contrast, using the knurled thumb screw on the DIC slider (Fig. 4-8/
4
). By adjusting
the DIC slider symmetrically around its middle position, you can render specimen details spatially as
though they were raised or recessed.
