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

Polarizer

Compensator – maintains

the cross Nichols

Polarizer – changes the

contrast.
