Used GATAN 691 #293770696 for sale

GATAN 691 is a state-of-the-art ion milling equipment designed for use in materials science applications. This system features a cross-section and backscatter preparation stage, a four-axis black-and-white microscope for visual inspection, and an advanced imaging stage with a digital camera for high-resolution imaging. The unit utilizes a focused ion beam (FIB) to produce areas that need to be prepared for analysis; FIB is a type of ion milling method that utilizes a scanning focused beam of ions to ablate and modify surfaces of materials. The FIB of 691 is uniquely tailored for sample sectioning or surface preparation, allowing for high precision and a high resolution. The main components of GATAN 691 include the accelerator, the cell, the crucible, the electrodes, and the accelerator head. The accelerator is driven by a high-voltage pulse and produces a slowly moving beam of charged particles that is then directed into the specially designed cell. Inside the cell, the beam bombards a sample with charged particles that, through ion milling, produce a flurry of ions or particles that interact with the surface of the sample. The crucible is where the sample is loaded and the electrodes direct the movement of the ion beam. Finally, the accelerator head provides direct FIB control in order to achieve precision and accuracy. 691 machine is also equipped with a computer-controlled four-axis black-and-white microscope for visual inspection. This microscope is used to identify any irregularities on the surface of the sample, such as deposits of ion milling chemicals, etch pits, or other surface features. The microscope is used to prepare surfaces for further study. The ion milling tool is also equipped with an advanced imaging stage that uses a digital camera to capture images of the surface of the sample. This digital camera is a dual-layer asset that captures images with a resolution of 2nm at its maximum resolution, allowing for very high-resolution images to be taken. GATAN 691 model is an invaluable tool for materials science applications. Its high-precision FIB, four-axis black-and-white microscope, and digital camera allow for highly detailed and accurate analysis of materials. Ultimately, 691 is an excellent equipment that can be used to increase our understanding of a wide variety of materials and their structure, composition, and properties.
