Atomic-Resolution Imaging and Analysis
The HD-2700 is an aberration-corrected 80-200 kV field emission gun scanning transmission electron microscope (STEM) with secondary electron (SE) imaging capability. Bulk and surface structures of specimen can be imaged simultaneously. Ultra-high resolution can be achieved for both STEM and SE imaging. The Hitachi corrector minimizes the user’s effort in doing aberration correction. Large solid angle EDS spectrum imaging are enabled.
- True atomic-resolution SEM imaging through correction of spherical aberration.
- Ultra low mag (100X) SEM imaging convenient for sample navigation
- Atomic resolution Bright-field, Dark-field, and SEM simultaneous imaging
- Diffraction contrast-enchanced imaging mode for defect observation.
- Bruker SDD EDS detector with 60 sq. mm area for a ~0.3 steradian solid angle
- In-situ heating holder heating up to ~1200 deg. C
- Selected-diffraction DF-STEM(analogue to dark field TEM)
