At last a use for one eurocent coins ... I notice I can get a nice darkfield by putting a eurocent on to the lower lens of the olympus swing out condenser. That way I can get darkfield up to 20x. But more surprising to me was the somewhat "DIC-like" effect I get with my 40x objective.
BTW can somebody confirm the lower picture is a shelled amoeba ? Species/Genus possible ? (Also of the diatom ?)
