The world’s first fully integrated SEM and fluorescence microscope


[text_output]By adding SEM contrast to your fluorescence imaging, structural and functional details can be obtained in a single image.

The integrated design makes the system easy to operate and extremely fast thanks to seamless switching between imaging techniques. The system also has the advantage of size and may be placed in any laboratory without the need for extra infrastructure.

Precision mechanics and the use of a proprietary automated alignment technique using the electron beam allows extremely precise, user-independent overlay of images with an accuracy of sub-50 nm.

The Delphi is the ultimate bridge between the fluorescence and electron microscopy world.[/text_output]

At a glance

  • Fully integrated, both in hardware and software
  • Easy to use and fast workflow, from sample loading to correlative imaging in less than a minute
  • Automated overlay using proprietary algorithm leading to perfect and unbiased overlays
  • No facilities required for installation



Typical application areas of the Delphi include whole cells cultured on cover-glass, as well as thin sections of cells, tissue or other biological material.[/text_output][text_output]Example application showing human umbilical vein endothelial cells stained for nucleus, actin and mitochondria, overlaid with high resolution SEM data. ►[/text_output]
