objective lens in the Hitachi S-4700 is a “snorkel” lens (Figure 2) which has low aberrations (described below), and it can accommodate large specimens. In addition, it can simultaneously accommodate both a lower (i.e., an E-T) and an upper (through-the-lens) secondary electron detector as described below, providing valuableThe Hitachi S-4700 is a field emission scanning electron microscope (FE-SEM). More powerful than a standard SEM, the S-4700, under optimal conditions, can magnify images upwards of 500,000 times and resolve features to 2 nanometers. In addition, a cathodoluminescence detector, backscatter electron detector and energy dispersive x-ray ... The subject of this tutorial, the Hitachi S-4700 FE-SEM, utilizes a cold cathode field emitter composed of a single crystal of tungsten etched to a fine point. In scanning electron microscopy, electrons escape the source …

HITACHI S-4700 SCANNING ELECTRON MICROSCOPE WITH EDAX X-RAY OPTION. Hitachi S-4700 FE SEM Field Emmission Scanning Electron Microscope with EDAX X-Ray Option. INCLUDES CENTAURUS DETECTOR, IBSS GROUP CV10X-DS ASHER RONTEC, XFLASH DETECTOR. Still in the Lab in working condition. It has been under Hitachi Service Contract. The FE-SEM in the ACMAL facility utilizes only an EDS system. EDS is the most common X-ray detector found on SEMs. Physically, the EDS detector has a shaft that penetrates the SEM chamber wall to place the sensor very close to the sample. It is easily recognizable with its liquid nitrogen tank. Liquid nitrogen is used to reduce electronic noise ...The S-4700 Cold Field Emission SEM incorporates a set of electrodes and plates positioned in the objective lens upper pole piece in close proximity to the upper secondary detector (figure 1). When a positive voltage is applied to the electrode plates, a high yield of secondary and backscattered electrons spiral up the column of the objective ...It is located inside the specimen chamber, attracting largely backscattered electrons that create a topographic signal. It collects secondary electrons from the specimen surface as well as the surrounding area. It provides a side view of the specimen, showing irregular surfaces. External components of the FE-SEM column.
