Abstract
A light interference experiment instrument is mainly used in experimental teaching in colleges and universities. The light interference experiment instrument comprises a Newton ring slider, a steel plate, magnetic supporting feet, a monochromatic light source, a semi-transparent semi-reflective mirror, a microscope, a CCD camera, a cable, a display, a guide rail, a CCD camera bracket slider, a microscope bracket slider, a Newton ring device and a micrometer adjusting device. One ends of the magnetic supporting feet are fixed on the Newton ring device, the other ends of the magnetic supporting feet are placed on a side face of the steel plate, and magnetic force of the magnetic supporting feet enables the magnetic supporting feet to be placed in any position of the side face of the steel plate together with the Newton ring device; the microscope bracket slider is equipped with the microscope; the CCD camera bracket slider is equipped with the CCD camera; and after the CCD camera is adjusted to be aligned with an eyepiece of the microscope, interference fringes captured by the CCD camera are accessed to the display through the cable and are displayed by the display.
