Spectra 200 – Transmission Electron Microscopy (TEM)

High throughput TEM and STEM microscope for all materials science applications.

Spectra 200 Scanning Transmission Electron Microscope

For scientists to advance their understanding of complex samples and develop innovative materials, they must have access to robust, precise instrumentation capable of correlating form and function, as well as resolving space, time and frequency.

Thermo Fisher Scientific introduces the Thermo Scientific Spectra 200 (S)TEM, the high-throughput, aberration-corrected, (scanning) transmission electron microscope for all materials science applications.

Spectra 200 Scanning Transmission Electron Microscope advantages

All Spectra 200 (S)TEM’s are delivered on new platforms designed to offer an unprecedented level of mechanical stability and highest imaging quality though passive and (optional) active vibration isolation.

The system is housed in a fully re-designed enclosure with a built-in on-screen display for convenient specimen loading and removal. For the first time, full modularity and upgradeability can be offered between uncorrected and single-corrected configurations with variable heights, allowing maximum flexibility for different room configurations.

Powered by the ultra-high-brightness cold field emission gun (X-CFEG)

The Spectra 200 (S)TEM can be powered by a new-cold field emission gun (X-CFEG). The X-CFEG has extremely high brightness (>>1.0 x 108 A/m2/Sr/V*), low energy spread, and can be operated from 30 – 200 kV. This provides high-resolution STEM imaging with high probe currents for high-throughput, fast acquisition STEM analytics. With the powerful combination of X-CFEG and S-CORR probe aberration corrector, sub-Angstrom STEM imaging with over 1000 pA of probe current can be routinely achieved.

High-resolution STEM imaging performance for all accelerating voltages

The combination of enhanced mechanical stability, the latest 5th order S-CORR probe aberration correction and the X-CFEG, gives the Spectra 200 (S)TEM high-resolution, high-contrast STEM imaging capability for all accelerating voltages. Additionally, Spectra 200 (S)TEM retains the wide gap S-TWIN objective lens as standard from the Themis product line, to ensure customers have a pole gap with “room to do more” without compromising on spatial resolution. In the images below, 48 pm resolution is shown on a wide gap S-TWIN Spectra 200 (S)TEM at 200 kV.

Unprecedented sensitivity with the Panther STEM detection system

STEM imaging on the Spectra 200 (S)TEM has been re-imagined with the Panther STEM detection system, which includes a new data acquisition architecture and two new, solid state, eight-segment ring and disk STEM detectors (16 segments in total). The new detector geometry offers access to advanced STEM imaging capability combined with the sensitivity to measure single electrons.

Advanced STEM imaging capabilities

The Spectra 200 (S)TEM can be configured with an electron microscope pixel array detector (EMPAD) or a Thermo Scientific Ceta Camera with speed enhancement to collect 4D STEM data sets.

New possibilities in STEM analytics with Spectra 200 S/TEM

The Spectra 200 (S)TEM has been configured to be a STEM analytics powerhouse. The extreme brightness and low energy spread of the X-CFEG, the latest generation, 5th order S-CORR probe corrector, the wide gap (S-TWIN or X-TWIN) pole piece with a portfolio of large solid angle and symmetric EDS detectors and the built-in EDX quantification engine in Thermo Scientific Velox Software makes STEM EDX on Spectra 200 (S)TEM fast, easy and quantifiable.

Energy Dispersive Spectroscopy

Energy dispersive spectroscopy (EDS) collects detailed elemental information along with electron microscopy images, providing critical compositional context for EM observations. With EDS, chemical composition can be determined from quick, holistic surface scans down to individual atoms.

3D EDS Tomography

Modern materials research is increasingly reliant on nanoscale analysis in three dimensions. 3D characterization, including compositional data for full chemical and structural context, is possible with 3D EM and energy dispersive X-ray spectroscopy.

Atomic-Scale EDS

Atomic-resolution EDS provides unparalleled chemical context for materials analysis by differentiating the elemental identity of individual atoms. When combined with high-resolution TEM, it is possible to observe the precise organization of atoms in a sample.

EDS Elemental Analysis

Thermo Scientific Phenom Elemental Mapping Software provides fast and reliable information on the distribution of chemical elements within a sample.

Electron Energy Loss Spectroscopy (EELS)

Materials science research benefits from high-resolution EELS for a wide range of analytical applications. This includes high-throughput, high signal-to-noise-ratio elemental mapping, as well as probing of oxidation states and surface phonons.

In Situ experimentation

Direct, real-time observation of microstructural changes with electron microscopy is necessary to understand the underlying principles of dynamic processes such as recrystallization, grain growth, and phase transformation during heating, cooling, and wetting.

Particle analysis

Particle analysis plays a vital role in nanomaterials research and quality control. The nanometer-scale resolution and superior imaging of electron microscopy can be combined with specialized software for rapid characterization of powders and particles.

Multi-scale analysis

Novel materials must be analyzed at ever higher resolution while retaining the larger context of the sample. Multi-scale analysis allows for the correlation of various imaging tools and modalities such as X-ray microCT, DualBeam, Laser PFIB, SEM and TEM.

Automated Particle Workflow

The Automated NanoParticle Workflow (APW) is a transmission electron microscope workflow for nanoparticle analysis, offering large area, high resolution imaging and data acquisition at the nanoscale, with on-the-fly processing.
