Manipulator for an optical or particle-optical apparatus

摘要

The invention is directed to a manipulator for an optical apparatus including a particle-optical apparatus. The manipulator is especially a diaphragm or specimen manipulator in an electron microscope. The component ( 4 ), which is to manipulated, is accommodated by a transfer body ( 2 ) movable relative to a spatially-fixed component ( 1 ) and the transfer body ( 2 ) includes a composite material having a high thermal conductivity while simultaneously having a vanishing or negative thermal expansion coefficient in the direction of the connecting axis (B-B) between the component ( 4 ) and the spatially-fixed component ( 1 ).
