Used GATAN 691 #293808870 for sale

GATAN 691 is a state-of-the-art ion milling equipment designed for the precise preparation of materials for advanced microscopic analysis. Ion milling is a process in which a surface is bombarded with ions and material is physically removed from the surface. This process prepares the surface for further characterization techniques such as atom probe tomography, transmission electron microscopy, scanning electron microscopy, and Auger electron spectroscopy. 691 is capable of controlling the direction, intensity, and duration of the ion bombardment. It also utilizes an in-situ broad beam of electrons to reduce the effects of temporary surface damage caused by the ion beam. This system is capable of producing smooth, flat surfaces with extremely fine resolution. The ion milling process can be tuned and optimized to achieve the desired surface quality and topography. GATAN 691 ion milling unit uses a powerful vacuum chamber to maintain proper environment during processing. The sample to be milled is placed in the chamber and is bombarded with ions of various energies, typically argon or oxygen. The ions slowly erode the sample, eventually producing a smooth surface with fine resolution. The ion beam can also be directed in a certain pattern to achieve a specific depth of penetration into the sample. 691 offers the highest level of reliability and repeatability, making it the ideal choice for a variety of applications. The machine can create finely polished surfaces with a surface area of up to 6 square inches. It also has exceptionally fast processing times, with some materials being able to be processed in as little as 30 minutes. The tool is also highly automated, allowing for controlled processing from the initial bombardment up to the final removal of debris. GATAN 691 ion milling asset is an ideal choice for scientific research purposes, as it offers an unparalleled level of precision and accuracy. The model can produce ultra-smooth surfaces with the most minute details preserved, making it ideal for applications like measuring atomic positions and studying nanoscale features. This equipment is also perfect for preparing materials for advanced microscopic analysis.
