Never heard of before. So if you're looking in the scope without
eyepiece but with the phase stops in the condenser, what do you see?
1 semi-opaque background with clear ring, 1 completely opaque
background with clear ring

Do you actually see a ring in the translucent ones??

Can anyone helop with advice about this condenser, please? It is CZ
with the serial number 4337802.
there is an open position, marked J, a darkfield stop , marked D, and 4
phase rings, marked 2, 3,2,3.
These differ in that two are translucent, and two are reflective.
Can anyone tell me what these different types of phase stop are for,
please? I assume that one pair is for normal phase, but the other?
Thanks for any information/advice/experience. I haven't got any phase
objectives to try it with yet, so am anxious to get suitable ones for
this condenser!

Many thanks to all for very helpful advice, hugo j
