MODEL NAME                :- JEM 2100F
MAKE                    :- JEOL ,JAPAN
Specification of the Instrument:

The JEM-2100F is an advanced high resolution field emission electron microscope equipped with cryo-pole-piece and OneView camera. The JEM 2100F is a next generation TEM that simplifies atomic level structural analyses in biology, medicine, and materials sciences as well as the semiconductor and pharmaceutical industries. It can be operated at variable voltages between 80-200 kV both in scanning transmission and transmission electron microscopy mode (STEM/TEM). It has a high brightness and high beam stability due to field emission electron source. The point to point resolution is 0.23nm. Standard techniques that are available include bright field/dark field imaging, high resolution lattice imaging and electron diffraction. In addition it is equipped with high angle annular dark field detector (HAADF) for Z-contrast imaging and JEOL energy dispersive spectrometer (EDS) for chemical analysis at nano scale.
