Performance & Power in a Flexible Platform
Hitachi High-Tech's scanning electron microscopes SU3800/SU3900 deliver both operability and expandability. The operator can automate many operations and efficiently utilize their high performance. The SU3900 is equipped with a large multipurpose specimen chamber to accommodate observation of large samples.
Features a graphical user interface offering easy operation and flexibility by:
The Zigzag function enables automatic acquisition of a continuous field of view. The Multi Zigzag function enables zigzag settings at multiple locations on the sample stage, allowing the acquisition of multiple high-magnification images at user-selectable regions of interest. These images can be montaged to create pixel-dense-micrographs by connecting the acquired images with the Viewer function.
The SU3800/SU3900 feature a high-sensitivity UVD. UVD can acquire images and CL information with secondary electron information by detecting the light generated by collisions of secondary electrons and residual gas molecules accelerated by a bias electrode.
With a 5-segment design, it is possible to observe composition images, 3D images, and topographic images from 4 directions without sample rotation. Due to the design and high sensitivity of the detector, high-resolution imaging with improved S/N retention is possible.
The SU3900 is equipped with a large multipurpose specimen chamber to accommodate observation of large samples.
The newly developed SEM/EDS integration system unifies stage location, condition setting, analysis, reports, and a series of operations from the SEM graphic user interface of the SU3800/SU3900. Controlling everything from the SEM graphic user interface improves throughput and reduces operator tasks.
Hitachi map 3D automatically combines 4 images acquired from different directions using the backscattered electron detector to construct a 3D model. Measurements such as height between two points, volume, and simple surface roughness (area roughness, line roughness, etc.) are possible. Since all backscattered electron data is collected in a single acquisition, it is not necessary to tilt the sample or adjust the field of view.
The SU3800/SU3900 feature IPI, which transfers SEM images to advanced image-processing software (Image-Pro® manufactured by Media Cybernetics Inc.). The operator can transfer data from SEM images to sophisticated image-analysis software with just one click.
