Interactive system of learning of optic geometric for Sience Museum.

The design of the equipment has slightly larger dimensions than its predecessor and a larger observation area, so that a larger audience can observe the demonstrations. As far as the demonstrations that are presented in this design, do not present changes with respect to the previous prototype. One of the significant changes in this design, is the ability to select two diaphragms of 1 and 5 slits in the light source, related to this, it was necessary to redesign the light source, looking for the yellow box to rotate around its own axis to allow the selection of the diaphragm, it was also necessary to implement a lever adjustment system, so that the light source remains fixed at a required angle. Another of the modifications in the system is that the system of rods for the assembly of the elements is no longer presented, changing it for a larger surface of aluminum on which all the optical elements will be mounted, having ası, greater area of incidence of rays from the light source, ası as well as space for the signaling of each demonstration. In relation to the functioning of the interactive system does not present changes with respect to the selection of the demonstration, but as for the source of light. In order for the rays or beam emerging from the light source to be at a desired angle, all that is needed is to misadjust the lever, position the light source by means of the yellow knob at the desired angle and then adjust the lever again. Then to select the desired diaphragm just turn the knob in any direction until the beam or beams emerging from the source of light coincides collinearly with the lines of the angles in the goniometer.
