概要（Overview）

The Hitachi IM4000Plus Ar ion milling system provides two milling configurations in a single instrument. Previously two separate systems were needed to perform both cross section cutting (E-3500) and wide-area sample surface fine polishing (IM3000), but with Hitachi's IM4000Plus, both applications can be run within the same machine. The IM4000Plus Ion Milling System utilizes a broad, low-energy Ar+ ion beam milling method to produce wider, undistorted cross-section milling or flat milling, without applying mechanical stress to the sample.
