SEM Has 61 Beams Working in Parallel
LISTED UNDER:
The MultiSEM 505 from ZEISS, a new scanning electron microscope (SEM), features 61 beams working in parallel, and offers a capture speed of 1220 megapixels per second at a pixel size of 4 nm. This high acquisition speed is used for imaging neural tissue in brain research where it is now possible to observe much bigger samples than before. ZEISS MultiSEM 505 is designed for continual operation and fitted with the intuitive ZEN Software.
Conventional SEMs use a single electron beam, which is guided over the sample surface and by acquiring pixel by pixel an image of the sample is formed. ZEISS MultiSEM uses 61 beams simultaneously, making it possible to acquire 61 images in parallel. Thus large areas can now be imaged very quickly and acquisition times are reduced from years to weeks.
