Abstract

The invention provides a sample platform and a microscope system. The sample platform is applicable to an electronic back-scattering diffraction-type work mode and a transmission electronic diffraction work mode. The sample platform includes a support frame, and a sample sink assembled on the support frame. The support frame includes a jack stand and a support rod. The support rod is connected with the jack stand. The jack stand forms an angle of 142 degrees with the support rod. When the sample platform is used, the sample platform is fixed on an object table of a secondary electronic microscope and the support rod is made form an angle of 90 degrees with the object table. Through a structure in which the angle between the jack stand and the support rod is designed to be 142 degrees and the angle between the support rod and the object table to be 90 degrees, when a sample is loaded on the sample platform for test analysis, through adjustment of tilting and/or rotation of the object table, a tilt angle between the sample and the horizontal plane can be adjusted in a large range so that switching between the electronic back-scattering diffraction-type work mode and the transmission electronic diffraction work mode can be carried out according to practical demands.

Description

technical field [0001] The invention relates to the technical field of sample stage manufacture, in particular to a sample stage and a microscope system. Background technique [0002] Electron backscattered diffraction technique is a testing technique based on secondary electron microscopy for grain size distribution and orientation distribution on the material surface. Usually, in the process of electron backscatter diffraction, the sample for electron backscatter diffraction needs to form an angle of 70 degrees with the horizontal plane, and electrons enter the sample at a grazing angle, so under this condition, the lateral resolution is greater than 100 nanometers, which is very Difficult to analyze grains smaller than 100 nm. Therefore, improving the lateral resolution of electron backscattered diffraction technology is a hot research direction now. [0003] Generally, the method adopted by those skilled in the art in order to improve the lateral resolution of electron...
