Cross Sectioning and Sample Preparation

Cross-sectioning and TEM sample preparation is frequently performed using our FIB-SEM, providing sub-micron accuracy when location is important. We also have a well equipped preparation lab, with mechanical and ion polishing machines, sputter coaters and a plasma cleaner. For more information on these techniques, click on the images below.
