Abstract: The invention is directed to a sample holder for a microscope. The sample holder comprises a sample chamber which is filled with an immersion liquid and in which a sample is located. The sample chamber has an upper opening. It further comprises means for translating the sample relative to a detection objective of the microscope, and means for rotating the sample around an axis of rotation extending in a substantially horizontal plane which encloses an angle other than zero degrees with the optical axis of the detection objective. In a sample holder of this kind, the sample is embedded in a transparent embedding medium having at least partially a greater solidity than the immersion liquid. Further, the sample chamber has means for horizontally supporting the embedded sample against the effect of gravity.
