Technical Field

[0001] The utility model relates to the technical field of test stands, and particularly relates to a magneto-optical Kerr test stand. Background Technique

[0002] When linearly polarized light (composed of left-handed circularly polarized light and right-handed circularly polarized light) is incident on a magnetic material and reflected, due to the different propagation speeds of the left-handed circularly polarized light and the right-handed circularly polarized light in the sample, a phase difference is generated. Coupled with the different absorption degrees of the left-handed circularly polarized light and the right-handed circularly polarized light, resulting in different amplitudes. After reflection by the sample, the phenomenon of converting into elliptically polarized light is called the magneto-optical Kerr effect.

[0003] At present, the magneto-optical Kerr test requires highly adjusting the test instrument. The traditional adjustment method is manual adjustment, which makes it easy to have errors in manual adjustment, resulting in a decrease in the accuracy of the test instrument. At the same time, manual adjustment is also relatively cumbersome and complex. Based on this, the utility model designs a magneto-optical Kerr test stand to solve the above problems.
