A cold stage for an electron microscope, said cold stage being arranged to reduce relative motion between the sample holder and the objective lens. The cold stage consists of an annular stainless steel body on which is coaxially bolted a plastic insulator ring with a plurality of spaced upstanding short vertical posts. A central arbor of gold-plated copper has outwardly projecting radial lugs engaged on and bolted to said posts. Connected to another radial lug projecting from the arbor is a laminated thermally conducting strap member consisting of 40 superposed thin flexible leaves of heat-softened copper, with a 180 DEG blend to absorb vibrations from the associated cold finger, or heat transfer rod, leading from a liquid nitrogen cooling source.
