Comprehensive optical demonstration system with built-in He-Ne laser. Top quality optical components for over 75 demonstrations. Demonstrate both ray optics and selected wave phenomena in a lighted room. The Laser Optics Demonstrator consists of a base unit with a built-in He-Ne laser, deflection system and ray optics board, and an accessory case with 30 optical quality glass components mounted on carriers, three magnetic base supports, and a mechanical stage for wave optics experiments. An extensive operator’s manual describes 51 ray optics demonstrations and 27 interference and diffraction experiments.
