Ultrahigh-Resolution and Analytical Capability
Hitachi’s Schottky emitter provides ultrahigh-resolution images and ultrafast microanalysis with high probe current.
Its 0.1kV imaging capability without stage bias expands the application range for beam-sensitive specimens.
A multitude of detectors and options are available to best suit the needs of any user.
Enhanced User Experience with Advanced Automation
The “EM Flow Creator“ software option allows users to configure repeatable SEM operation sequences.
Various SEM functions can be assembled in the EM Flow Creator’s window by a drag-and-drop method and then saved as a recipe for later use.
Once a recipe is configured, automated data collection under the set conditions can be performed with high accuracy and repeatability.
New Display and Interface Features
Dual monitor configuration supports a flexible and highly efficient workspace.
Display and save 6 signals simultaneously in order to acquire more information in less time.
Acquire up to 40,960 x 30,720 pixels of high-resolution information.*
Large FOV + High Pixel Resolution
Ultrathin section BSE images of Rat Cerebral Cortex
Top-left image was acquired with >120 μm of FOV. The yellow rectangle field in the image is also shown in right image with an increase of digital magnification.
Even after digitally enhancing the original image more than 20 times, the structures of organelle were clearly visible and high quality was maintained.
High-resolution images up to 40,960 x 30,720 pixels are available (*) on SU8700 and SU8600.
