The JEOL JEM-2800 provides optimal image quality and maximum analytical resolution in the class of the 200 kV TEMs. The Schottky field emission cathode delivers high, long-term stable currents for outstanding performance data even at extremely small beam diameters down to 0.05 nm.
The instrument includes electron optics completely free of rotation, which allows for the simplified allocation of TEM images and diffraction patterns. The Windows™ based user interface is intuitive and easy to operate.
The newly designed side-entry goniometer with five-axis motorization permits programmable saving and recalling of positions. Piezo elements for the x/y direction of the goniometer are integrated as a standard for absolute jerk-free movement of the specimen.
