In case of nanofocus tubes, the focal spot is further minimized by means of a special setup consisting of lenses and diaphragms. The user may choose from a range of operating modes, each providing different tube voltages and image resolutions. The most potent operating mode offers detail detectabilities down to 200 nm (0.2 µm).
Since there was no customary generator providing the stability necessary for such extraordinary feature recognition, phoenix|x-ray set out to develop its own unique high-voltage generator.
