Used PHILIPS / FEI Quanta 200 FEG #9251682 for sale

PHILIPS / FEI Quanta 200 FEG is a scanning electron microscope (SEM). It combines the use of a highly advanced field emission gun (FEG) with unique features such as digital imaging and scanning electron diffraction. FEGs typically use up to 10 times lower acceleration voltage than regular SEMs, and can produce images of up to 20 nanometers in detail. The Quanta 200 features a high-resolution field emission gun that has a minimum electron-beam spot size of about 1-2 milli-radians. The FEG also offers higher current density, which leads to higher signal-to-noise ratio than other electron guns. This makes it capable of producing high-quality images of both thin and thick specimens. The Quanta 200 also features a digital imaging equipment in order to produce high-resolution images of various samples. The imaging system can capture from high-resolution to low-resolution images, depending on the user's needs. Additionally, this SEM also features a special scanning electron diffraction (SED) mode, which enables the user to analysis crystalline structures with great accuracy. The Quanta 200 also offers a range of accessories that can be used for various applications. These include: a special high-resolution secondary electron detector that can detect electrons with energies between 1 and 30 eV; an automated scanning area stage for scanning large objects; and a polarized electron beam unit for analyzing magnetic materials. Finally, the Quanta 200 is also capable of environmental scanning electron microscopy (ESEM) for imaging specimens in a range of conditions. This includes operation in vacuum, high humidity, and high temperatures. Additionally, the machine can maintain a high-quality image in non-vacuum conditions due to its low electron spot size. In conclusion, FEI Quanta 200 FEG is a scanning electron microscope that offers unparalleled performance. With its state-of-the-art FEG, digital imaging, and SED capabilities, the Quanta 200 can provide detailed images of any specimen from crystalline structures to large objects. It can also runs under a range of operating conditions, making it versatile and adaptable to any type of situation.
