JEOL’s Three Dimensional Image Software is a program that takes stereo pair SEM images and constructs a three dimensional (3D) image of the sample surface. From this 3D image, height and contour maps can be created to provide cross sectional shape and height data. The easiest approach to creating stereo pair images is to take two images of the same area but at different tilt angles. Images can be taken with any detector, at any magnification, with high or low accelerating voltage and even in low vacuum mode. With this software, any offset to the stereo pair images can be corrected for automatically and an anaglyph image or 3D model of the surface created.

The Tilt Rotation Motor Drive Holder (TRMH) is a motorized specimen holder designed for the JCM-7000, NeoScope™. This holder provides tilt and rotation capability during image observation. Installing this holder allows for 4 axis motor control.

TEM is an ideal technique for analyzing metals to gain an understanding of their structural and elemental properties on the sub-micrometer to atomic scale.

Imaging of nanostructured materials requires a new design of SEM that provides ultimate resolution for both imaging and microanalysis, combined with the ability to image any type of material. An innovative new SEM column design from JEOL Ltd. utilizes a hybrid lens (combination electrostatic and electromagnetic lenses) in conjunction with a Through-The-Lens (TTL) detection system to provide the user with ultimate imaging and analytical performance. The hybrid electrostatic/electromagnetic lens minimizes magnetic field effects at the sample and is relatively impervious to stray magnetic fields. The lens is characterized by low values for the spherical and chromatic aberration coefficients. Moreover, the proven Aberration Correction Lens (ACL) technology automatically maintains small probe size for both imaging and microanalysis.

SEM offers a unique ability to visualize specimen surface morphology (via secondary electron imaging), as well as obtain crystallographic or Z-contrast information (via backscatter electron imaging) while at the same time performing chemical composition analysis via energy dispersive spectroscopy (EDS). In the past, this simultaneous acquisition was often hindered by deficiencies in detector and column design, that would not allow sufficient count rates or sufficient resolution for adequate analysis at various working distances.
