1. DIC components To set cross Nichols: only include polarizer and
analyser in the optical path. (Find a slot without
any prism on condenser and objective, swing out
compensator)
Remove the eyepiece and you should be able to see
this:
Analyser
Shear prism at objective
Wollaston prism at condenser
Senormont compensator
Polarizer
Compensator – maintains
the cross Nichols
Polarizer – changes the
contrast.
compensator
Set screw for adjusting cross
Nichols

2. Phase contrast – there are set-screws for aligning phase ring.
To use Phase contrast, just use the matching phase ring (on the condenser turret) according to the
objective chosen.
