The JEOL 200CX is a high-quality general purpose 200KV transmission electron microscope of traditional (analog) design. It has a high-resolution side-entry pole-piece and goniometer which has achieved a point-to-point resolution of about 0.25 nm, but the information limit is far better than this - the microscope is capable of resolving 0.14 nm lattice fringes. It has a 1.3Mpix AMT digital camera.
A hot stage is available for this instrument. A video-recorder capability in the imaging software allow for the dynamic recording of experiments.
The microscope operates with a tungsten filament, to allow for fast turn-on, useful, for example, for checking samples for use in other microscopes, or for a quick investigation which does not require the capabilities of the other instruments.
This instrument is also used for initial training of users.
