Spherical Aberration Corrected STEM/SEM HD-2700

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.


High-resolution STEM imaging

HAADF-STEM image 0.136 nm, FFT image 0.105 nm (HR lens*)

Cs-corrected SEM imaging

The Hitachi HD-series dedicated STEM is equipped with a secondary electron (SE) detector as standard configuration; this enables imaging the specimen surface directly in addition to obtaining interior structural information of specimen via the transmitted electron beam. SE imaging offers fine dimension measurements of thicker samples not compatible with STEM.
Spherical aberration correction pushes the SEM resolution to an unprecedented, true atomic level.

The principle of SE detection

solid-angle should be hyphenated

A large solid-angle SDD (100 mm2) provides greatly enhanced EDS analytical sensitivity compared with previous models, as well as higher throughput of elemental analysis in a shorter data-acquisition time.
