Multifunction laser capable of emitting a spot beam with vertical adjustment for diffraction experiments, a horizontal beam for the study of wave propagation, or three parallel vertical beams for geometric optical experiments. Equipped with a magnetic base for use on a whiteboard and an input modulation of the laser beam to study information transmission by fibre optics. NB: This product is meant for geometric optical practicals that are peformed 50cm away from the point of source. 1 horizontal light beam, 1 or 3 vertical parallel light beam
