ZEISS MultiSEM 706
The World’s Fastest Scanning Electron MicroscopeUnleash the acquisition speed of 91 parallel electron beams – to image samples in the centimeter scale at nanometer resolution. This unique scanning electron microscope is designed for continuous, reliable 24/7 operation. Simply set up your high-throughput data acquisition workflow and MultiSEM will acquire high-contrast images automatically.

Blazing Fast. Nanometer Sharp.
Experience the fastest acquisition speeds ever achieved at nanometer resolution. The unique MultiSEM system uses 91 electron beams in parallel, significantly boosting your overall imaging speed. For example, capturing a 1 mm² area at 4 nm pixel size takes less than two minutes. With an incredible acquisition rate of over 3 TB per hour, you can image large volumes (> 1 mm³) while maintaining precise nanometer resolution.

The Technology Behind ZEISS MultiSEM


Multiple Electron Beams and Detectors in Parallel
MultiSEM achieves high imaging speed by employing multiple electron beams and detectors in parallel. The key to this approach is a finely tuned detection path (red) collecting a large yield of secondary electrons used for imaging with a multiple detector array. Each beam carries out a synchronized scanning routine at one sample position, resulting in a single sub-image. The electron beams are arranged in a well-characterized hexagonal pattern. By merging all sub-images together, the final, full image is formed. A parallel computer setup is used for fast data acquisition ensuring a high total imaging speed. Experiment control and image acquisition are fully separated in the MultiSEM system to guarantee full performance.
