Whether you’re working with large industrial materials or smaller research samples, the SU3800 and SU3900 specimen chambers with their eucentric stages have you covered.

SU3800: Accommodates samples up to 200 mm in diameter, 80 mm in height, and 2 kg in mass.

SU3900: Designed for extra-large samples, you can load specimens up to 300 mm in diameter, 130 mm in height, and 5 kg in mass. Ideal for imaging large-scale industrial components.

With these spacious chambers, you can skip the time-consuming step of cutting or modifying large samples down to smaller sizes, allowing for faster sample preparation.

Both models feature advanced eucentric motorized stages with 5 axes (X, Y, Z, tilt, and rotation) for precise positioning. Stages can be fully retracted from the specimen chamber for easy, collision-risk-free positioning of even large and heavy specimens.

SU3800: Sample stage moves across 0–100 mm (X-axis) and 0–50 mm (Y-axis), with a Z-axis range of 5–65 mm. At maximum, a disk with 130mm diameter can be fully observed.

SU3900: The larger SU3900 stage provides greater flexibility, with ranges of 0–150 mm (X-axis), 0–150 mm (Y-axis), and 5–85 mm (Z-axis), making it ideal for large or irregularly shaped samples. In total, a 229 mm diameter region can be imaged.

Both the SU3800 and SU3900 are equipped with SEM MAP, a powerful tool for navigating large specimens.

SEM MAP displays a zoomable optical color photo, matching the maximum SEM-observable region of the specimen (130mm Ø / 229mm Ø). The photo is acquired automatically during chamber evacuation, allowing you to center any point of interest under the electron beam with just a mouse click. SEM overviews can be locally patched instantly for enhanced navigation accuracy.

SEM MAP also works with SE and EDS detectors. The tool gives you a clear understanding of whether an observed specimen location is properly oriented towards the desired detector for the best signal collection. Total clarity is achieved by having the SEM MAP display rotation-linked to the actual SEM or stage rotation settings.

Hitachi’s automation and support features are designed to take the stress out of operating an SEM, no matter your experience level.

A user-definable operating condition library loads an entire working environment (optics setting, vacuum mode, detector settings, stage conditions), instantly setting the desired conditions for completing a specific task.

Automated functions for focus, brightness, contrast, and more allow you to start imaging immediately after sample loading.

The Schottky field-emission column version comes with fast and fully automated optics alignment, executable on the spot for typical real-world specimens.

For the tungsten-hairpin filament source, Intelligent Filament Technology (IFT) dynamically optimizes filament heating and monitors filament conditions in real-time, ensuring optimal performance and high filament lifetime.

Multi Zigzag functionality automatically acquires and stitches together multiple high-magnification images, giving you a detailed, wide-area view of your sample.

Automated workflows mean less manual adjustment and more time for data collection. EM-Flow Creator lets you define fully automated workflows for even complex imaging tasks, without coding experience.

From academic research in biology and nanotechnology to industrial applications like quality control in automotive and materials science, the SU3800 and SU3900 are ideal for a range of use cases.

Optional accessories like heating/cooling/tensile stages, analytical instrumentation, or a STEM holder expand the range of applications, enabling in-situ observations and dynamic sample analyses.
