TRAINING-DEMONSTRATION INSTALLATION FOR LEARNING OF OPTICAL PHENOMENA (VERSIONS) AND TEST OBJECT FOR ITS REALIZATION

摘要

The invention relates to the field of training devices designed for school research, labs and educational demonstrations on geometric and wave optics in the course of physics. Summary of the utility model: to set up for the study and demonstration of optical phenomena comprising an optical bench on which are fixed in series along the optical axis of the laser transmitter, the test object is coated with a diffractive structures and the screen for the observation of optical phenomena, the test object is mounted on the optical bench via alignment tool which provides him the opportunity to move in a vertical plane, according to the utility model, a laser emitter mounted on a cylindrical a support rotatably in a horizontal plane, the test object is in the form of a flat circle with radially angular arrangement of diffractive structures thereon and mounted in the frame rotatably about the optical axis for positioning the diffractive structure investigated. In addition, the test object for study and demonstration of optical phenomena containing substrate disposed thereon rows of diffractive structures according to the utility model, made in the form of a flat circular plate with an opaque coating, and the diffraction structures are applied to it in the form of at least two circular concentric rows and one in the center. The technical result - the expansion capabilities, increased ease of installation operation, improve the accuracy of adjustment of the position of the investigated optical object, facilitating the alignment position transmitters and display devices.
