ABSTRACT:
An apparatus for releasably and adjustably mounting a specimen in an electron microscope. A specimen-holding unit is releasably and fluidtightly mounted in an evacuatable chamber and abutting the lens of the electron microscope in the mounted position. The unit is held in place by the pressure differential between the chamber and the atmosphere when the chamber is evacuated. The specimen-holding unit comprises a rotatable specimen-holding shaft disposed eccentrically within a rotatable support member. The specimen is variably positioned under the electron beam by the rotation of the member and the rotation of the shaft with respect to the member.
