Creating a perfect image requires a combination of theoretical knowledge and practical experience and a balance between many factors. This process may encounter some challenging issues in the use of  Electron Microscope. Astigmatism is one of the most difficult corrections to make in an image and requires practice. The middle image in the following figure is a correctly focused image after astigmatism correction. The left and right images are examples of poor astigmatism correction, resulting in stretched stripes in the image. To achieve precise imaging, the cross-section of the Electron Beam (probe) should be circular when it reaches the specimen. The cross-section of…

Focused Ion Beam (FIB) is a microfabrication instrument that utilizes an electron lens to focus an ion beam into a very small size for precision cutting. Liquid Metal Ion Source The ion source is the heart of the FIB system, and the accurate focusing of the ion beam begins with the emergence of liquid metal ion sources. The ions generated by liquid metal ion sources, mostly utilizing gallium (Ga) as the metal material, have high brightness and petite source sizes. Liquid metal ion sources are formed by the field-induced ion emission from a liquid metal surface under a strong electric…
