Laboratories that are focused on advanced materials characterization need access to next-generation methods and will push analytical tools, such as scanning electron microscopes (SEMs), to extreme capabilities.
A majority of these laboratories are multi-user facilities, where users with different levels of experience are accommodated. Time spent on the microscope is valuable, and excess time devoted to training, alignments, image optimization, or maintenance should be prevented.
With the latest Thermo Scientific Apreo 2 SEM, access to high-performance imaging and analytics is expanded to all levels of microscopy know-how.
Thermo Scientific ColorSEM Technology is an exclusive live elemental imaging capability that provides compositional data continuously through the most intuitive interface. ColorSEM Technology prevents all the hassle related to the typical implementations of energy-dispersive X-ray spectroscopy (EDS) and provides ease of use and unparalleled time to result.
Thanks to Thermo Scientific SmartAlign Technology, the Apreo 2 SEM places relatively smaller demands on laboratory managers and users. Thermo Scientific SmartAlign Technology is a self-aligning optics system.
Using Thermo Scientific FLASH technology, the Apreo 2 SEM also automates the image fine-tuning procedure. FLASH Technology can make any required corrections to the stigmators, to lens centering, and to the final focus of the image.
The integration of all these technologies ensures that even users who are new to the field of electron microscopy can access the exceptional performance of the Thermo Scientific Apreo 2 SEM.
Moreover, the Apreo 2 SEM is the only instrument that has a 1 nm resolution at an analytical working distance of 10 mm. This means long working distance will no longer lead to substandard imaging. With the Apreo 2 SEM, any user can confidently obtain excellent results.
