Ultra high resolution field emission scanning electron microscope

Thermo Scientific Apreo 2 SEMUltra high resolution field emission scanning electron microscopeEquipped with real-time elemental imaging function and advanced automatic optical system, gray area resolution is achieved, allowing you to no longer worry about microscope performance and focus more on research itself.

The Thermo Scientific Apreo 2 SEM has multifunctionality and high-quality imaging performance. It adopts an innovative final lens design and introduces an electrostatic final lens, supporting high-resolution detection inside the tube. Even for magnetic samples, it can achieve excellent imaging and analysis performance. The all-new Apreo 2 SEM has further optimized its ultra-high resolution imaging capability on the basis of its original performance, and added many new features to enhance its usability. Apreo 2 SEM introduces SmartAlign technology on a durable SEM platform, eliminating the need for manual adjustment by users. Additionally, FLASH automatically performs fine adjustment work, allowing for necessary lens centering, astigmatism correction, and focus correction with just a few mouse movements. In addition, Apreo 2 SEM has a resolution of 1nm at a working distance of 10mm, and a longer working distance no longer means low resolution imaging. The system can also upgrade its real-time element spectrum/image imaging function. For decades, the inherent element analysis process of traditional SEM-EDS has increased the efficiency of element analysis by more than twice. Apreo 2 SEM， Any user can easily obtain analysis results.
