Dimpler Grinder

The Gatan Model 656 Dimple Grinder is a precision instrument used to produce circular dimples in materials such as ceramics, semiconductors, metals, and combinations thereof. The principle application is in the preparation of TEM specimens. When specimens are mechanically dimpled prior to final thinning, the finished specimen has a more uniform thickness, has a larger than usual electron-transparent area, and is very robust with a thick rim surrounding the central thin region.
