Hitachi HT7710 120kV BF/DF Scanning Transmission Electron Microscope

STEM imaging in the HT7700 is performed using Bright Field (BF) and annular Dark Field (DF) detectors. Contrast can be adjusted with push-button ease by choosing between diffraction-contrast or Z-contrast conditions. STEM imaging inherently reduces the impact of inelastically scattered electrons on image blur, allowing thicker samples to be imaged at low kV. Combining precision beam control of the STEM with EDX analysis enables simultaneous elemental mapping and imaging to see the elemental distribution.


Continuing more than 70 years of microscopy innovation, Hitachi offers the HT7710 STEM with maximum performance and productivity for in-situ analysis.

The HT7710's radical design incorporates the ergonomics and user friendliness of a SEM with the advanced resolution and analytical capabilities of a TEM/STEM. It features completely digital imaging supported by a redesigned viewing chamber which accommodates Hitachi's brightfield and darkfield STEM detectors.
