U17300_L.jpgA multitude of experiments can be performed which optimally explore and demonstrate the fundamental principles of geometrical optics. Experiments on the following topics are possible: Law of Refraction and Law of Reflection Total reflection Determining the focal length of mirrors and lenses Lens laws Optical defects and their correction (long-sightedness and short-sightedness) Actions of various optical devices (telescope, camera, microscope) Optical components such as lenses, mirrors, prisms, light sources and silk-screen foils are coated with magnetic foil and can be attached to a magnetic board or a whiteboard (U10030 or U10031) in seconds. Experiments can be performed without the need to dim the room lighting. A diode laser with 5 beams, serves as the light source (not included). The number of emitted beams can be selected using a drilled metal plate placed at the front of the laser.
