A machine for automatic electrolytical thinning of specimens for TEM. Tenupol 5 is equipped with a scanning function, pre-defined voltage range is scanned to determine the current density curve. This curve is used to to define the correct polishing voltage for the thinning process. Specimens with a diameter of 2.3 and 3 mm are polished from both sides simultaneously to achieve a thin foil with a centre hole as small as possible. The thinning is controlled by an infrared light source, stopping the process as soon as the first light can pass through the established hole.
