概要（Overview）

The HD-2700 is an 80-200 kV field-emission-gun scanning transmission electron microscope (STEM) with secondary electron (SE) imaging capability. Bulk and surface structures of a specimen can be imaged simultaneously. With the option for a probe-forming aberration corrector, 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* and atomic-spatial-resolution EDS* and EELS spectrum imaging* are enabled.
