Sample holder system with freely settable inclination angles
A sample holder system for holding a microscopic sample in a microscope system comprises a first and a second rotation element, which are rotatably connected to one another. The side surfaces of the two rotation elements in each case enclose an angle α, with the result that the rotation elements have a wedge-shaped cross section. The second rotation element is configured to receive a sample, while the first rotation element can be rotatably connected to a holder receiving surface. The rotation elements are each rotatable by an angle β about a rotation axis. The inclination of the third side surface on which the sample can be received is settable by combining all of the involved angles α and β.
