Used HITACHI S-4100 #8483 for sale

HITACHI S-4100 is a type of scanning electron microscope (SEM) used in research, industrial and medical applications. This scanning electron microscope allows researchers and scientists to observe and analyze the structure, chemical composition and electrical properties of a given specimen at high resolution. In addition to being used for research, S-4100 can be used for industrial and medical applications such as inspecting materials for manufacturing defects, viewing and examining supercomplex device structures, and diagnosing diseases. In general, the system consists of a column unit which is the electron optical column, an electron gun, a specimen stage and a detector unit. Gas is used in the column chamber to achieve the necessary vacuum for the electron beam to travel. The electron gun produces the electrons which are then accelerated by the acceleration voltage and sent through the column where they interact with the specimen and create secondary electrons. The specimen stage is a moveable holder of the sample on which the electron beam is focused. Lastly, the detector unit is used to collect and analyze the resulting signals from the interaction of electron beam and the sample. HITACHI S-4100 is equipped with two imaging modes, namely, secondary electron imaging (SEI) and backscattered electron imaging (BEI). SEI is best used for material surface inspection and analysis where the appearance of the surface features can be viewed. BEI is used for analyzing crystallographic artifacts and for the detection of contrast between materials. The system is capable of imaging at different magnifications from 10 megapixel- to 30 megapixel-level, with a maximum resolution of 12 nanometers. S-4100 is also equipped with an automated focus system for high-speed auto-focus of the detectors. In addition, the specimen stage can be automated and computer-controlled for reproducible results in a repeatable experiment. Multiple control modes are available and can be adjusted according to the application. Overall, HITACHI S-4100 provides outstanding imaging and analysis capabilities, along with automation and computer functionality. This makes S-4100 ideal for both research and industrial applications in a variety of fields.
