As the choice of these lenses is quite limited, different depth ranges of brain tissue are accessed with different lens lengths while fine focusing is done with the focus adjustment ring that comes with each cannula. As cannulas might be re-used it is advisable to get a set of these rings as spare parts. The working distance of D, V and E imaging cannulas is 80 µm.
