Abstract
A multi-degree-of-freedom sample holder, comprising a housing and a rotating shaft, is disclosed. A frame is provided between the housing and the rotating shaft, and the frame is coaxial with the housing and rotating shaft. The present invention has multiple degrees of freedom such as high-precision translational freedom of the sample along the X-axis, Y-axis and Z-axis, and 360° rotation of the sample around the axis, etc. The sample is always aligned with the sample holder shaft during the rotation, and the static electricity accumulated on the sample can be led out.
