Prisma E SEM Flexible and easy to use SEM for the widest range of samples, ideal for multi-user laboratories

Scanning Electron Microscopy is indispensable when microscale material insight is required. SEM is not only capable of creating excellent surface topography images, it also provides materials contrast and access to crystallography and elemental composition. Building on more than 60 years of electron microscopy developments, including the first computer controlled and environmental SEMs, Thermo Fisher Scientific has continued to advance the capabilities of SEM with the release of ColorSEM Technology. Now, for the first time, scanning electron microscopes can produce images with live,...

Introduction The Thermo Scientific™ Prisma™ E SEM is a highly flexible scanning electron microscope (SEM) capable of remarkable all-around performance under a variety of conditions. With its low vacuum and environmental SEM (ESEM) modes, it is fully equipped to analyze charging, outgassing or otherwise difficult samples. Highlights • Easy and quick sample loading for multiple and/or heavy samples • Simplified sample navigation with the Thermo ScientificTM Nav-Cam™ Camera and navigation montage • Ease of use thanks to User Guidance and an Undo function • Excellent image quality with advanced...

Prisma E SEM workflow Sample loading The Prisma E SEM provides extensive sample flexibility; it not only accommodates multiple samples weighing up to a total of 5 kg, but it can fit large samples due to its interior chamber width of 340 mm. Standard multi-sample SEM holder The Prisma E specimen chamber accepts a maximum sample diameter >200 mm on a multi-sample stub holder, which allows up to 18 samples to be loaded on 12 mm stubs, or up to 6 samples on 25 mm stubs. Multipurpose sample holder* The multipurpose sample holder provides a fast way to fit a range of different sample types with...

Nav-Cam Camera* The Nav-Cam Camera allows you to quickly traverse the whole sample holder with pointand-click navigation, letting you reach your area of interest with ease. As the camera displays a color image it’s easy to differentiate between different samples, letting you take advantage of any multi-sample holder. Fully integrated into the Prisma user interface, the Nav-Cam Camera enables you to track saved positions as well as the current imaging location. Additionally, digital zoom is available via the UI to enlarge features of interest. Navigation montage The navigation montage...

Improved user interface The improved xT user interface is designed to allow for full customization. Toolbar icons can be repositioned, added and removed, letting every user have their own personalized interface based on their experience and needs. Novice users will never get lost in too many options and experienced users will have the ability to get the best results they can by properly tuning the system. Of course, the default layout can be restored at a click of a button. Notably, several new functions and options are now available including undo/redo, column and scan presents as well as...

xT UI highlight: User Guidance User guidance functionality provides a set of easy-tofollow steps to help novice users get started and to ensure optimal use of the microscope. Each step is hyperlinked directly to the xT UI, allowing users to execute functions through the guide or simply use the guide as a learning tool. Adjust and taking the final image Setting imaging parameters Sample loading Sample preparation xT UI highlight: undo/redo Undo/redo functionality allows you to recover multiple operations, encouraging experimentation in both novice and experienced users and saving time during...

Features ColorSEM Technology Elemental information is now at your fingertips with ColoSEM Technology which provides integrated, realtime EDS to your SEM data 4x faster than conventional elemental analysis systems. ColorSEM Technology enables the microscope UI to display live color images based on the sample’s elemental composition. This is an entirely new approach to elemental analysis, providing a highly intuitive way to characterize your samples. With ColorSEM Technology, EDS spectra are acquired simultaneously with secondary electron (SE) and/or backscattered electron (BSE) signal, even...

Benefits of ColorSEM Technology Complete information Intuitive elemental analysis Cement imaged with conventional SEM (left) and with ColorSEM Technology (right). In the conventional backscattered electron image, the presence of areas with different elemental compositions is not evident, while the ColorSEM image (acquired in 60 seconds) provides a higher level of information. ColorSEM Technology is always on, meaning compositional differences will no longer go unnoticed. ColorSEM provides a qualitative point & ID, even available during live scanning. Shorter time to results Reliable results...

Advanced scanning strategies: SmartSCAN Technology Thermo ScientificTM SmartSCAN™ Technology offers different imaging and scanning strategies to optimize image acquisitions and settings (256-frame averaging or integration, line integration and averaging as well as interlaced scanning). Frame integration enables cumulative noise reduction with integration over a specified number of frames. Line integration scans each line repeatedly several times. Collected signal data is integrated and displayed as an actual image line. This imaging method reduces sample charging (compared to a single pass...

Beam deceleration mode Beam deceleration (BD) is an optical mode where the specimen is biased with a negative potential (max. stage bias = -4 kV) and primary electrons are decelerated before they land. Thanks to an accelerating voltage higher than the landing energy, the final resolution is improved. BD also enables the detection of low angle backscattered electrons (BSE) that move nearly parallel to the surface of the sample, enhancing surface topography and eliminating charge from the image. 10 μm Beam deceleration off (left image) and on (right image). On this polymeric nanofibers...
