[0002] The surface magneto-optical Kerr effect measuring device is an instrument used to measure the magnetic properties of the material surface. The magneto-optical Kerr effect refers to the phenomenon that under the combined action of the magnetic field and the light field, the refractive index or absorptivity of the material changes with the change of the magnetic field. By measuring this effect, the magnetic properties of the material can be understood.
[0003] In the prior art, the sample placement table of the magneto-optical Kerr effect measurement device lacks an adjustment structure. After the sample is placed on the surface of the placement table, the distance from the observation imaging lens will be different due to the different thicknesses of the samples. The clarity of the imaging is adjusted simply by adjusting the position of the imaging lens, which is easily limited by the maximum adjustment stroke. When imaging and observing thicker or thinner samples, the difficulty of imaging adjustment increases, and the adjustment stroke is even exceeded, resulting in blurred imaging. Based on this, the utility model designs a surface magneto-optical Kerr effect measurement device to solve the above problem. Utility Model Content
