Darkfield Imaging Principles

Using a darkfield microscopy, we see some details that we could not observe using brightfield technique. To know the main difference between bright-field an dark-field , think of seeing some fogs an drain drops under light shine. That is a natural darkfield imaging.

Darkfield objective lenses and condensers are the core elements of the darkfield imaging:
