The Model 200 Dimpling Grinder is a state-of-the-art mechanical grinder for preparing electron microscopy samples. It is indispensable when ion milling is used for final specimen thinning. Once the specimen is prethinned by dimpling, ion milling must remove only a relatively small amount of material.
High-quality specimens for transmission electron microscopy need to be both rugged and have a large electron transparent area for analysis. Dimpling is a rapid technique that involves rotating both the grinding wheel and the specimen. This combination of motions produces a specimen with only its central area reduced to a thickness of a few microns.
