Spectra - Model Ultra S/TEM -Scanning Transmission Electron Microscope

Unfortunately, acquisition at different accelerating voltages on the same sample without losing the region of interest—all during a single microscopy session—is not possible. At least, until now.

Imagine a Thermo Scientific Spectra™ 300 S/TEM:

• That can truly be operated at different voltages (all the voltages between 30 and 300 kV for which alignments were purchased) in a single microscopy session
• Where changing from an accelerating voltage to any other one takes about 5 minutes
• That can accommodate a radically different EDX concept with a 4.45 srad solid angle (4.04 srad solid angle with an analytical double tilt holder)

With the new Spectra Ultra S/TEM, the accelerating voltage becomes an adjustable parameter, just like probe current, and the massive Ultra-X EDX system enables chemical characterization of materials too beam-sensitive for conventional EDX analysis.

The Spectra Ultra S/TEM is delivered on a platform designed to offer an unprecedented level of mechanical stability quality through passive and (optional) active vibration isolation.

Like the Thermo Scientific Spectra 200 S/TEM and Spectra 300 S/TEM, the system is housed in a fully redesigned 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.
