Description

Technical Field

[0001] The utility model relates to the technical field of regulating devices, in particular to a magneto-optical Kerr measurement regulating device. Background Art

[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, a phase difference is generated due to the different propagation speeds of the left-handed circularly polarized light and the right-handed circularly polarized light in the sample. In addition, the different absorption levels of the left-handed circularly polarized light and the right-handed circularly polarized light cause different amplitudes. After reflection from the sample, it is converted into elliptically polarized light. This phenomenon is called the magneto-optical Kerr effect.

[0003] The magneto-optical Kerr effect is an important magneto-optical phenomenon that is widely used in the characterization and research of material magnetism. However, traditional magneto-optical Kerr measurement devices have problems such as insufficient precision and complex operation when adjusting the position of optical devices, which affects the accuracy and stability of the measurement results. Based on this, the utility model designs a magneto-optical Kerr measurement and adjustment device to solve the above problems. Utility Model Content

[0006] Preferably, four fixing blocks are fixed at equal intervals on the bottom end of the slider body, and the top surface of the slide plate is provided with a slot that matches the shape of the fixing blocks. The fixing blocks are fixedly connected to the slide plate by fixing screws.

[0010] Preferably, the fixing block is in an L-shape, and the fixing block and the fixing grooves on the sliding plate that match the shape of the fixing screws are both provided on the same side as the side of the slider body.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] (1) The utility model sets a sliding plate at the bottom end of the slider body and drives the screw to rotate through a servo motor.

[0023] Among them, two outer sleeves 10 are symmetrically fixed to the bottom of each slider body 2, and an inner slider 9 that matches the position of the outer sleeve 10 is fixed on the top surface of the connecting plate 7. The inner slider 9 is slidably connected to the inside of the outer sleeve 10. The shape of the internal thread groove of the threaded moving block 8 is semicircular, and the radius of the internal thread groove of the threaded moving block 8 is the same as the radius of the screw 4. The threaded moving block 8 is located directly below the screw 4. The stroke of the cylinder 6 is greater than the distance between the threaded moving block 8 and the screw 4, which makes the movement of the slider body 2 more convenient.

[0024] See also Figure 1-4 Four fixed blocks 14 are equidistantly fixed to the bottom of the slider body 2, and a slot matching the shape of the fixed block 14 is opened on the top surface of the slide plate 5. The fixed block 14 is fixedly connected to the slide plate 5 by a fixing screw 15, so that the slide plate 5 is easy to disassemble.
