The invention relates to an integrated tester for wave optics, wherein the tester is an integrated experiment teaching instrument. The tester is composed of a light source, an objective table, an optical screen, a vernier plate, and a dial. An optical screen track is welded to a support arm and is welded with the dial. When a handle is rotated, the dial and the optical screen track rotate together; an alpha vernier and a beta vernier are designed on the vernier plate in a diametric mode; and reticules of 0 degree to 360 degrees are marked on the periphery of the dial uniformly. When measurement is carried out, numerical values corresponding to the alpha vernier and the beta vernier are read and then averaging is carried out to obtain location of the optical screen, thereby achieving an objective of angle measurement. The tester is mainly used for demonstration of a two-slit interference experiment, a single-slit diffraction experiment, a circular hole diffraction experiment, an optical grating diffraction experiment as well as Malus law verification and brewster angle measurement and the like. The tester has advantages of convenient usage, clear experiment phenomena, convenient demonstration of optical path leakage, low cost, and precise measurement.
