Accurate tip etching is achieved by the W-Tek semiautomatic etching device for the production of tungsten tips with an extremely small apex radius by etching in solution or by the lamella process. The etched tips are suitable for use in STM, FIM, FEM and SEM applications. The electronic control unit offers user-friendly facilities for monitoring of the etching voltage or current to provide optimum sensitive control of the etching process.
