I want to make an inquiry

Through the automatic repeated use of FIB to prepare cross-sections and perform SEM observations, a series of continuous cross-sectional images are collected, and the three-dimensional structure of specific micro-regions is reconstructed. Using the most ideal lens barrel layout, from advanced materials, advanced equipment to biological tissues-in a wide range of areas to achieve high-precision three-dimensional structure analysis that is difficult to match with traditional models.

◆ SEM observation of vertical incidence cross-section can faithfully reflect the original sample structure

The SEM lens barrel and the FIB lens barrel are at right angles to each other to realize the normal incidence SEM observation of the FIB processed section.

The old FIB-SEM adopts oblique cross-section observation method, which will inevitably cause the cross-sectional SEM image to be deformed and to deviate from the field of view when collecting continuous images. The right-angle structure can avoid such problems.

By stably obtaining images that faithfully reflect the original structure, high-precision three-dimensional structure analysis is realized.

At the same time, the FIB processing section (SEM observation section) is parallel to the sample surface, which is conducive to establishing links with optical microscope images and other data.

◆ Cut&See/3D-EDS*1/3D-EBSD*1 can support various materials

Cut&See

From biological tissues and semiconductors to magnetic materials such as steel and nickel-support high-resolution and high-contrast observations at low acceleration voltages.

When switching between FIB processing and SEM observation, there is no need to reset conditions, and continuous images of cross-sections can be collected efficiently.

Extract cross-sectional image, 3D reconstruction image

3D-EDS*1

Not only supports cross-sectional SEM images, but also supports continuous collection of element distribution images of a series of cross-sections.

The optional silicon drift type large solid angle EDS detector*1 can shorten the measurement time and collect element distribution images at low acceleration voltages.

3D-EBSD*1

Configure the SEM/FIB/EBSD detector*1 in the most ideal way to realize 3D-EBSD without moving the sample stage between FIB processing and EBSD analysis. Because there is no need to move the sample stage, the accuracy and efficiency of three-dimensional crystal orientation analysis can be greatly improved.
