A device for an optically controlled micro-manipulation of biological
specimens includes at least one micro-manipulator with at least one
motor-displaceable cytotechnical instrument holder elements, and a
microscope which has at least one functional motor-displaceable element
coupled with the motor-displaceable holder in such fashion that, using a
control element, a common displacement or adjustment of the holder and a
displacement of the at least one functional element of the microscope can
be executed in a coordinated fashion so that upon changing a size of a
field of view by changing a microscope objective lens, a covered range of
displacement of a cytotechnical instrument using the holder is adapted to
a new field of view.
