概述

is the top-of-the-line SEM equipped with cold FE electron source and in-lens objective lens with least aberration, and achieves the world's highest SE resolution of 0.4nm. In addition to high resolution STEM with 0.34nm resolution, EELS and diffraction that are usually considered difficult for SEM can also be supported. The SU9000 is HITACHI's new premium SEM. It features unique electron optics, with the sample positioned inside a gap between the upper and lower parts of the objective lens pole piece. This so-called true in-lens concept - combined with the next generation of HITACHI's cold field emission technology - guarantees the highest possible system resolution (SE resolution 0.4 nm @ 30 kV, 1.2 nm @ 1 kV without requiring beam deceleration technology [0.8nm with beam deceleration]) and stability.
