Used FEI Expida #9284884 for sale

FEI Expida is a state-of-the-art ion milling equipment designed for the ultra-precise shaping of surfaces. It utilizes milling technology to achieve horizontal and vertical banding of a surface layer with sub-nanometer scale precision. Ion milling works by driving charged ions at the workpiece and harvests them away to alter the workpiece's material. Expida uses a focused ion beam (FIB) and a specialized stage to accurately position the workpiece and then apply its proprietary ion milling technology. The FIB is an electron gun-like device that produces a steady beam of ions that can be directed with precision to the surface of the workpiece. The beam is focused down to a few hundred nanometers wide and is guided by computer-controlled electromagnets. This allows the milling precision to be adjusted to the needs of the application. FEI Expida's stage is a mechanical platform that supports and moves the workpiece in three axes. It features a translation range of up to 35 mm in the X, Y, and Z axes, along with precision scale resolution of 10 nm. The stage is equipped with vibration-reduction control and high-resolution optics for precise viewing of the sample surface. It also has a high-vacuum system with two stages of filtration to prevent external contaminants from entering the unit and damaging the workpiece. Expida features an intuitive user interface that gives users control of all aspects of the milling process. The Fein Interface (FEI Skin) provides an interactive way to configure the machine parameters for a wide variety of applications. This includes selecting the ion milling technique, adjusting the milling conditions, and monitoring the milling process in real-time. FEI Expida is an ideal tool for researchers and industry professionals who require a reliable, repeatable, and ultra-precise mean of fabricating high-performance components. This is due to its reliable hardware, accurate control asset, and intuitive user interface. This combination allows users to shave off individual nanometers with excellent repeatability for optimum surface structure and integrity.
