Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sample test benches, in particular to a magneto-optical Kerr effect measurement sample test bench. 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] Current magneto-optical Kerr effect measurement samples often require individual samples to be placed in front of the laser. This testing method often requires frequent placement of different samples in front of the laser when testing multiple samples, which makes the sample replacement process more cumbersome and complicated, thereby affecting the testing efficiency of multiple samples. Based on this, the utility model designs a magneto-optical Kerr effect measurement sample test bench to solve the above problem. Utility Model Content
[0004] The purpose of the present utility model is to provide a magneto-optical Kerr effect measurement sample test bench to solve the problem raised in the above background technology that the current magneto-optical Kerr effect measurement samples often need to be placed individually in front of the laser. When testing multiple samples, this testing method often requires frequently placing different samples in front of the laser, which makes the process of replacing samples more cumbersome and complicated, thereby affecting the testing efficiency of multiple samples.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a magneto-optical Kerr effect measurement sample test bench, comprising a test bench main body and a laser main body, two laser bodies are arranged on the top surface of the test bench main body, two cylinders are symmetrically fixed to the bottom end of the inner part of the test bench main body, a lifting frame is fixed to the top surface of the two cylinders, a first servo motor is fixed to the top surface of the lifting frame, the output end of the first servo motor extends to the top surface of the test bench main body, an irradiation table is fixed to the output end of the first servo motor, and a clamping frame is fixed to the side of the irradiation table.
[0006] Preferably, a second gear is fixed to the bottom end of one of the laser bodies, a pulley is fixed to the bottom end of the other laser body, a second servo motor is fixed to the bottom end of the inside of the test bench body, another pulley is fixed to the output end of the second servo motor, the two pulleys are connected by a transmission belt, and a first gear is fixed to the end of the other pulley away from the second servo motor, and the first gear is meshed with the second gear.
[0007] Preferably, the irradiation platform is in the shape of a regular hexagon, and the clamping frame is fixed to two sides of a side surface of the irradiation platform.
[0008] Preferably, an outer rod is symmetrically fixed to the top surface of the lifting frame, an inner rod is slidingly sleeved inside the outer rod, and the top surface of the inner rod is fixed to the bottom surface of the test bench body.
[0009] Preferably, the outer sleeve rod and the inner sleeve rod have the same length, and the inner circle radius of the outer sleeve rod is the same as the outer circle radius of the inner sleeve rod.
[0010] Preferably, each of the cylinders is located below the outer rod, and the cylinder stroke is equal to the length of the outer rod.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] (1) The utility model fixes the irradiation table at the output end of the first servo motor, and then drives the irradiation table to rotate by the first servo motor, so that the samples on different sides of the irradiation table are moved to the front of the irradiation table in turn, and the lifting frame is driven to move by the cylinder, so that the height of the irradiation table can be easily adjusted. This solves the problem mentioned in the above background technology that the current magneto-optical Kerr effect measurement samples often need to be placed in front of the laser individually. When testing multiple samples, this test method often requires different samples to be frequently placed in front of the laser, which makes the process of changing samples more cumbersome and complicated, thereby affecting the test efficiency of multiple samples.
[0013] (2) The second servo motor drives the pulley to rotate, so that the pulley drives the second gear and the transmission belt to rotate, so that the second servo motor drives the two laser bodies to rotate toward each other at the same time, making it easy to control the angles of the two laser bodies during rotation adjustment, avoiding the problem of the angles being unable to be adjusted simultaneously during manual rotation adjustment.
