The invention relates to the technical field of experimental instruments, and discloses an adjusting device for an automatic focusing light path. The adjusting device comprises a base, wherein an electric sliding table and a precision optical electric lifting table are respectively mounted and fixedly connected to the middle of the top surface of the base; the top surface of the precision opticalelectric lifting table is fixedly connected to the bottom end of a supporting rod; the top end of the supporting rod is fixedly connected to the middle of the bottom surface of a housing; a reflectoris fixedly connected to the middle of the housing in a sleeving mode; and a position sensor and an infrared distance sensor are respectively mounted on the left side and the right side of the top surface of the housing. According to the adjusting device for the automatic focusing light path, the information such as the angle and the height of laser incidence is calculated through a chip, then theangle of the reflector is automatically adjusted through a micro motor, the height of a focusing device is adjusted through the lifting table, and the position of the focusing device is automaticallyadjusted through the small-size electric sliding table, so that rapid and accurate focusing can be realized, and the adjustment of the laser light path is simple and efficient.
Description
technical field [0001] The invention relates to the technical field of experimental instruments, in particular to an adjusting device for an autofocus optical path. Background technique [0002] The laser optical path focusing device is mainly used for focusing when adjusting the laser optical path in the laboratory. In the prior art, the laser optical path adjustment mainly relies on manual adjustment. Before transmitting the laser to the next reflector, it is necessary to move the mirror frame to reflect Adjust the position of the mirror and adjust the height of the next lens by adjusting the telescopic rod on the frame. At the same time, it is necessary to adjust the angle of the mirror through the lens adjustment knob on the frame so that the laser can hit the mirror. Center, to achieve the purpose of focusing, in order to make the optical path focus more accurately on the next lens, it is necessary to use the diaphragm and the light adjusting paper. operating experienc...
