SIULAS Optics Experiment Box Model - Physics Optical Experiment Kit - Reflector Refraction Triangular Prism Convex Lens Concave Mirror Linear Light,White,10cm

Physics Optical Experiment Kit :High quality lens kit, three way linear light for light path demonstration. Direction Can Be Fine-Tuned:Adjust the direction of the light head so that the light direction is as parallel as possible to ensure the experimental effect. Three-Way Switch To Control Separately:Three independent switches, can be adjusted individually any one way of light, can do both lens convergence diffusion experiment, and also can do refraction reflection experiment. Mgnetic Adsorption:Strong magnet on the back, can make the experimenter adsorbed on the iron blackboard, more convenient for demonstration experiments. Battery Powered:Battery compartment on the back, powered by 2 x 7 dry cell batteries.
