Abstract

The invention relates to a sample carrier for a sample (70). Said sample carrier comprises a supporting base (10), a carriage (20) having a receiving region (30) for the sample (70), the carriage (20) being supported on the supporting base (10), a guide (40), the carriage (20) being movably arranged along the guide (40), and a disc (60) that is rotationally movable about an axis of rotation (50), said disc being operatively connected to the carriage (20), wherein a center (65) of the disc (60) is located outside of the axis of rotation (50).

First claim

The invention claimed is:

1. Sample carrier for a sample, comprising:
a supporting base;
a carriage having a receiving region for the sample, wherein the carriage is supported on the supporting base;
a guide, wherein the carriage is arranged for movement along the guide; and
a disc operatively connected to the carriage and rotatable about an axis of rotation, wherein a center of the disc is located outside the axis of rotation,
characterized in that
the carriage has an opening in its receiving region, wherein a sample pad is arranged in the opening, the sample pad being transparent in at least one optical spectral range;
the disc has an opening; and
a drive wheel has an opening, wherein a common axis as a visual axis runs through the opening of the carriage, through the opening of the disc and through the opening of the drive wheel.

2. Sample carrier of claim 1 , wherein the drive wheel is rotatable about a second axis of rotation and operatively connected to the disc, and wherein a center of the drive wheel is located on the axis of rotation of the disc.

3. Sample carrier of claim 2 , wherein the axis of rotation of the rotatable disc coincides with the axis of rotation of the drive wheel.

4. Sample carrier of claim 2 , wherein the drive wheel is operatively connected with a rotary drive.

5. Sample carrier of claim 1 , wherein the disc or the drive wheel comprise at least partly a magnetic material.

6. Sample carrier of claim 1 , wherein the carriage or the guide comprise a non-magnetic material.

7. Sample carrier of claim 1 , wherein the sample pad is formed entirely of an optically transparent material.

8. Sample carrier of claim 1 , wherein the sample pad protrudes from the opening of the carriage.

9. Device for processing a sample comprising a sample carrier according to claim 1 and a grinding unit.

10. Device of claim 9 , wherein an axis of rotation of the grinding unit encloses an angle of greater than 10° with the axis of rotation of the rotatable disc or perpendicular to the axis of rotation of the drive wheel.

11. Method for processing a sample, comprising:
providing a device for processing a sample according to claim 9 ;
placing a sample on the sample pad;
translationally moving the sample in a first plane; and
grinding the sample, wherein the grinding unit is moved in a second plane, wherein the second plane encloses an angle of greater than 50° with the first plane.
