FIELD: physics.;SUBSTANCE: invention relates to means for studying optical phenomena and can be used for laboratory works and experiments to study laws of optics. At the bottom of the casing with a cover there is a lodgment with a plane-parallel plate, screen, mirror, means to study optical phenomena. Means for studying optical phenomena are mounted in the riders. Optical bench is in the form of inequilateral channel bar, on the inner side of the wide base of which there is a fixed scale-line from magnetic material, and on the outer side - plastic dampers for installation of the optical bench. Each rider is formed by a post, made of a plate with a slot for fixing on the optical bench and interaction with at least one side of at least one narrow base of the channel bar and the post of the channel bar of the optical bench. Magnets are secured on the rider base to fix the rider on the optical bench. Screen is made of a plate with a slot for fixing on the optical bench. Lenses are rigidly connected to the riders. Light source has a light-emitting diode, which is connected to a constant voltage source through a resistor.;EFFECT: technical result is higher accuracy of experiments.;11 cl, 30 dwg
