Very good phase contrast effect. Which particular Lomo objective did you use?

Thanks a lot ; I used a
LOMO x40 phase
and a last photo without the blue filter ; so far i dont have any phase condenser : i've just drawn a phase annulus on the frosted filter and put it into the filter holder of the condenser ; and adjusted the height in order to get superimposed both the image of the annulus with the phase plate .

they are still available on ebay and my microscope cant work on Köhler illumination and nevertheless I can make the phase objectives work fine !
