Product overview A hardwearing optical glass equilateral prism with a stable stand, designed for handson learning and repeated use. The large, easy to hold shape provides comfort and safety during demonstrations and experiments. Ideal for classroom lessons, laboratory activities, and individual STEM exploration. Key benefits Clear results: Made from optical glass for clarity and minimal distortion, so light dispersion and refraction are easy to observe. Durable for repeated use: Hardwearing glass resists surface wear and maintains optical performance over time, suitable for regular classroom or lab use. Ergonomic and safe: Large, easy to hold design fits comfortably in student hands and helps reduce accidental drops during experiments. Stable setup: Supplied stand keeps the prism steady for precise demonstrations and consistent results. Educationally focused: Equilateral geometry produces predictable refraction and spectrum separation, helping learners understand core optics concepts. Function and performance Material: Optical glass provides clear transmission of light and consistent refractive behavior. Shape: Equilateral triangular prism geometry is ideal for demonstrating refraction, dispersion into the visible spectrum, and internal reflection. Usability: The prism and stand combination allows both handheld exploration and stable tabletop demonstrations. Compatible uses and applications Classroom physics demonstrations: Use with white light sources to show refraction and spectrum formation during lessons on light and optics. Student experiments and labs: Suitable for handson activities that require clear, repeatable optical behavior and a stable setup. Science fair projects and STEM at home: Portable and easy to handle for individual investigations into the properties of light. What customers need to know Designed for educational and experimental use with visible light sources commonly used in classrooms and labs. The large size and stand make it practical for group demonstrations and repeated handling by students. Built from optical glass to provide durable, long lasting clarity for learning environments. Package includes Equilateral optical glass prism Stable stand for tabletop demonstrations This prism is a practical, durable tool for teaching and exploring basic optical principles, offering clear visual results and a handson experience that supports learning and experimentation.
