Balplan Phase COntrast Condenser

#1 Post by microb » Mon Sep 21, 2020 8:04 pm

Does the Balplan condensers for phase contrast (Turret 31-55-41 or LWD 31-55-32) have multiple lenses inside? Is it jsut the condenser lens on the top with phase contrast mask below then iris? Or is there light collmination lens in there too?

The condenser in fig 12-1 has a lens below the iris.
