Leitz 1st generation Ortholux DarkField?

[dzarren]

I have one of the first generation Ortholuxes, and I am very interested in doing darkField microscopy.

Most things I see online suggest the Darkfield condenser, but how can I use my microscope with the Berek Condenser to do Darkfield?

Where in the optical train do i place a circular blockade? Can I place it right on the glass plate below the condenser, or must i place it somewhere else?



Is it possible to do darkfield with the setup i have currently? ( I need better and brighter lighting, but asides from this)

Thanks for reading!

I do think that those early 'black' Ortholux are quite beautiful - congratulations.
