Abstract
Electron microscopy of biological structural research has made signifi cant advances. These advances were the stimulus to develop an electron microscope containing most of the desirable features and methods for high resolution cryo-electron microscopy. The new instrument is a modi fied commercial Philips CM 20 FEG electron microscope equipped with a helium-cooled cryoobjective from Siemens. This paper presents the esse ntial features and research possibilities of this new microscope named ''SOPHIE'' (acronym for Superconducting Objective in a PHI-lips Elect ron microscope).
