Section: claims

1. A specimen holder comprising:a transmission surface point,a position where a specimen is mounted,a X-axis movement remote interval area located between the transmission surface point and the position where the specimen is mounted,a specimen holder portion extending from the transmission surface point on a side of the transmission surface point that is opposite the position where the specimen is mounted,wherein the transmission surface point is linked to a X-axis direction movement mechanism of the specimen which can transfer a X-axis movement force from a goniometer to the X-axis movement remote interval area, wherein the X-axis movement remote interval area in the main body material of the specimen holder is made of a low thermal expansion coefficient material. 2. A specimen holder according to claim 1, wherein the low thermal expansion coefficient material comprises any elements belonging to group 4, 5 or 6 in the periodic table of the elements. 3. A specimen holder according to claim 1, wherein the low thermal expansion coefficient material is made by any elements belonging to group 6 in the periodic table of the elements. 4. A specimen holder according to claim 1, wherein the low thermal expansion coefficient material comprises tungsten or a tungsten based alloy. 5. A specimen holder according to claim 1, wherein the low thermal expansion coefficient material is designed without using lead. 6. A specimen holder according to claim 1, wherein an alloy including tungsten is a 94W-4Ni-2Cu or 94W-2Ni-2Cu. 7. A specimen holder movement device having a specimen holder according to claim 1. 8. A specimen holder movement device according to claim 7, wherein the main material of a tube for holding the specimen holder is made of a low thermal expansion coefficient material.
