Key benefits Provides a safe, durable teaching tool kit with a plastic lens material for reliable classroom and home study use. Enables handson exploration of fundamental optical concepts, helping students understand how light behaves and how lenses and prisms affect it. Compact and practical design suited for demonstrations, experiments, and project work without the need for additional gear. What's included Lens set: Biconvex Lens; Single Concave Lens; Double Concave Lens Accessories: Glass Tile; Triangular Prism The package also includes additional items as indicated (etc) Adjustable light source Threeway linear light source is adjustable to direct light in different angles Adjustment is performed with a screwdriver to set the light direction precisely Supported optical experiments Refraction of light Convex lens refraction Lens refraction Prismatic refraction Other related optical demonstrations and experiments Use scenarios Classroom demonstrations: teachers can show how light bends, how lenses form images, and how prisms disperse light in a controlled, repeatable way. Student handson learning: learners perform experiments to observe optical principles directly, reinforcing theory with practice. Science fair or project work: the kit supports practical optics projects, enabling clear demonstrations and buildyourown experiments. Materials and construction Lens components made from plastic material for safe handling and repeated use. Designed as a practical teaching tool kit to support optics education in both formal and informal settings. Notes Includes a threeway linear light source with screwadjustment for light direction control. Suitable for use in classrooms, laboratories, or home learning environments.
