Abstract
The present invention relates to a glass plate (2) for use in a device (1) for stretching sample sections having a sectioning knife, the glass plate (2) being arranged at the back (3) of the sectioning knife in such a way that a defined gap (4) for reception of the sectioned sample is formed between the back (3) of the sectioning knife and the plate (2), the glass plate (2) possessing, at least on one of its longitudinal sides (21, 22), edges (211, 212; 221, 222) ground and polished to optical flatness.
Claims5
A device (1) for stretching sample sections, the device comprising:
- a sectioning knife having a back (3);
- a glass plate (2) arranged at the back (3) of the sectioning knife in such a way that a defined gap (4) for reception of a sample section is formed between the back (3) of the sectioning knife and the plate (2);
- wherein the glass plate (2) comprises a first longitudinal side (21) having a first pair of longitudinal edges (211, 212) and a second longitudinal side (22) having a second pair of longitudinal edges (221, 222), wherein the longitudinal edges of at least one of the first pair of longitudinal edges (211, 212) and the second pair of longitudinal edges are ground and polished to optical flatness, having a roughness <5 nm RMS.
