The space-saving and lightweight TM3030 can be conveniently installed on a tabletop*. No cooling water is needed, so installation is quick and easy and requires only a standard 100-240 V AC power supply.
Imaging with the TM3030 couldn’t be simpler. Pressing the “Start” button automatically turns on the beam, adjusts focus, brightness and contrast, as well as displays the image at an easy-to-view starting magnification of x100.
When a non-conductive sample is observed with a high-vacuum SEM, electrons accumulate on the specimen surface causes charge-up, preventing imaging. In order to avoid the charge-up damage, the sample is usually coated with a thin layer of metal prior to observation. This process is not only time-consuming, but also interferes with optical imaging of surface details as well as EDX analysis. The TM3030 overcomes this problem with “charge-up reduction mode.” This mode uses low-vacuum functionality to dissipate the charge.
By utilizing a low vacuum level inside the specimen chamber, more gas molecules are present. These gas molecules "G" can collide with the electron beam to generate positive ions "+" and electrons "e". Each positive ion "+" can be neutralized by one of the excess electrons "-" on the specimen surface. In this way the excess electrons on the surface of the sample are removed and the charge-up effect is eliminated or reduced.
The 5 kV accelerating voltage allows observation of surface details. It offers not only traditional topographic imaging, but also compositional imaging information. The 5 kV observation condition is further enhanced throughout high magnifications by improving the electron optics.
These functions will be utilized to enhance image quality at any observation condition modes and will be very effective for high-magnification specimens.
The TM3030Plus is equipped with a premium secondary electron detector and a backscattered electron detector which have been incorporated in FE-SEM or VP-SEM. Note: The TM3030 has a backscattered electron detector only.
These detectors can be operated effectively under low-vacuum conditions and can conduct both SE and BSE image observation without metal coating.
Both the TM3030 and TM3030Plus feature a BSE detector with 4 independent segments. By adding or subtracting signals from segments in different combinations, it is possible to emphasize compositional or topographic details in the image, as well as to produce shadowed images which highlight the sample from a particular direction.
Optional 3D-View software can generate three-dimensional views of the sample without sample tilting and/or alignment. It uses the 4 directional surface profiles from the signals acquired with each segment of the 4-segment backscattered electron detector.
The large specimen stage allows the mounting of a specimen up to 70mm in diameter and 50mm thick.
XY specimen motion 35mm.

TM3030Plus has a premium SE detector which has been incorporated in FE-SEM or VP SEM, and well-accepted by users as a high-sensitivity detector. It can be operated effectively under a low-vacuum environment and allows for quick SE image observation without specimen preparation.
The TM3030Plus allows for effective image analysis with dual signals in one image; displayed as one combined SE signal providing surface rich information and BSE signal for compositional information.
5 kV, Standard mode,
Magnification: ×1.0 K
The Energy Dispersive X-ray Spectrometer (EDX) for the Hitachi TM3030 series is equipped with the latest SDD (silicon drift detector), a large detection area (30 mm2), and multiple elemental analyses such as point/area analysis, line scan and mapping.
Uncoated sample observation brings seamless operation for the two signals through element mapping.
15 kV, Standard mode,
Magnification: ×3.0 K
A larger detection area allows less beam damage, lowering electron beam drift and charge-up reduction, and makes it possible to conduct observation for uncoated specimen.

When a filament is blown, changing the filament is rather easy. Remove the filament from the Wehnelt cap and simply attach a new filament assembly. Since the new filament is pre-centered at our factory, no adjustment is necessary. After attaching the filament assembly to the electron gun, it will be necessary to align the beam according to the on-board instructions for beam alignment.
