Molecular Analysis Facilty ToolDimple Grinder Make/Model: Fischione 200 Full Description The Fischione Dimple Grinder is an intermediate step in the preparation of hard (conventional) materials for TEM analysis. Dimple grinding follows planarization and polish and precedes ion-milling. This mechanical grinder thins only the central area of a TEM sample and leaves the outer edge thick enough to handle with tweezers. The area of interest can be precisely positioned at center using a 40X optical microscope. Final thickness at the center of the sample is just a few micron and can be quickly ion polished to remove scratches. Capable of both 1-sided and double-sided dimple grinding with 1um resolution. Prethins TEM samples up to 200um thick in preparation for ion polishing.
