Multiple-mode, high-resolution environmental SEM

With its range of vacuum levels, the Thermo Scientific Prisma E SEM helps you analyze a huge range of materials in high resolution, in their natural state and with complete confidence. This includes wet, hot, dirty, and outgassing samples. Also featured is through-the-lens differential pumping and simultaneous secondary electron and backscattered electron imaging in all modes.

The Prisma E SEM allows you to easily set up the acquisition for a wide range of materials such as cement, solar cells, or geological materials that are commonly known to be outgassing and beam-sensitive.

Faster, smarter materials analysis with the Prisma E SEM

In addition to expanding the scope of your experiments, the Prisma E SEM enables you to achieve this  quickly and efficiently. A simple interface (with integrated user guidance), coupled with built-in automation, make this system simple to learn. And if mistakes are made, just use its undo function.


Integrated EDS analysis for elevated elemental characterization

The Prisma E SEM makes elemental analysis  intuitive and efficient. The integrated EDS capability provides always-on analytical capability, with no time-consuming switching between systems.  The Prisma E SEM offers an easy, user-friendly way to obtain live composition-based image coloring.
