Used GATAN 691 #9250406 for sale

GATAN 691 is a highly efficient ion milling system that is used to create thin surface layers for nanostructured materials research applications. It is designed for parallel multi-channel ion beam milling over a large area, providing a uniform surface and structure across samples, whereas other technologies - such as chemical etching - will often result in a non-uniform structure. 691 relies on an ion source, a beam splitter, and an electrostatic deflector to collide the ion beam with the target surface and to create a uniform thinning layer. The ion beam is first divided into several channels using the beam splitter, which helps to create a uniform thinning layer across the entire sample. The beam is then directed to the electrostatic deflector which deflects the ions in a predetermined angle, again helping to create a uniform thinning layer over the entire sample. GATAN 691 also comes with interactive software, allowing users to configure the ion beam parameters and design the patterns for thinning. 691 has been specifically designed for nanostructured materials research, and this is reflected in its features and capabilities. Its high-voltage ion source enables a high milling speed, and this is further enhanced by its patented beam software algorithms which enable precise targeting and improved feedback. The deflection system and beam splitters are designed to minimize the ion beam energy spread over the sample. This helps to ensure an even thinning of the surface layer, while also minimizing any structural or material damage. Furthermore, the system can be calibrated to achieve the desired uniformity in ion beam parameters, which helps to ensure consistent results across different samples. GATAN 691 also features reliable 'ion energy drift' characterization, and precise feedback-controlled beam current. This helps to provide the required accuracy and speed for milling, while ensuring that the necessary uniformity requirements are satisfied. Finally, 691's modular and standard-compliant design ensures that it can be used in various research applications, with the range of features and settings adapted to the specific needs. GATAN 691 is an incredibly efficient and useful tool in nanostructured materials research, and its sophisticated design makes it an ideal choice for creating uniform thinning layers. With its powerful ion source, beam splitting capabilities, electrostatic deflectors, and feedback processing, 691 is unparalleled in its performance, offering reliable results with excellent surface uniformity.
