Anoptral contrast- The meopta has more or less co-operated with me today and we have pictures to show for our efforts. After much huffing and puffing I managed to get the mirror, condenser and objective lenses aligned; sort of, just about, almost.
The Meopta’s condenser is still a tad out of alignment but I think I have got away with it.
Anoptral phase contrast is much like normal phase contrast as far as set up goes. You need Kohler illumination and you need to use a phase telescope to align phase rings on the condenser turret with phase rings in the objective. The main difference is that with anoptral phase contrast the phase plates are a sooty brown colour. This reduces halos around your phase objects and gives a rather soothing brown background. Very easy on the eyes..
