2021 Optical Glass Triple Triangular Prism with Stand for Physics Light Spectrum Teaching A precision optical prism kit designed for classroom demonstrations, lab exercises, and hobby experiments that explore refraction, dispersion, and the visible light spectrum. The set includes a triple triangular prism made from optical glass and a stable stand for tabletop use. Key benefits Clear, repeatable demonstrations of light dispersion and spectral separation that make abstract optics concepts visible and easier to teach. Stable mounting with included stand reduces handling errors and allows hands experiments and measurements. Optical glass construction delivers good clarity and consistent refractive behavior for accurate classroom and laboratory observations. Compact and portable design makes it easy to move between classrooms, labs, and demonstrations. Simple to set up and align with standard light sources, making it accessible to instructors, students, and hobbyists. What makes it useful Designed specifically for light spectrum teaching and basic optics experiments, so it addresses common classroom needs for demonstration pieces that show refraction, dispersion, and internal reflection. The triple triangular prism geometry provides multiple refraction paths and viewing angles, enabling a variety of experiments without changing components. The included stand secures the prism at a fixed height and angle, improving repeatability and reducing setup time during lessons. Product attributes Function: Demonstrates refraction, dispersion, splitting of white light into a visible spectrum, and related optics phenomena. Material: Precision optical glass for good transparency and consistent refractive index. Configuration: Triple triangular prism configuration for versatile light paths and demonstrations. Accessory: Supplied with a stable tabletop stand for fixed positioning and hands use. Model: 2021 optical prism kit suitable for teaching and experimental use. Compatibility: Works with standard classroom and laboratory light sources such as white LED lamps, halogen lamps, and focused sunlight; compatible with standard optics benches and mounting setups where the included stand can be placed. Typical applications and use scenarios Classroom demonstration: Place a white light source behind the prism mounted on the stand to project a clear visible spectrum onto a screen or wall during a lecture on dispersion and wavelength. Laboratory exercise: Use the prism to measure angles of refraction and dispersion for student experiments on refractive index and Snell law, taking advantage of the fixed stand to maintain alignment between trials. Science fair or hobby experiments: Create reproducible spectral displays, compare light sources, or explore polarization and internal reflection with a reliable, portable prism setup. Who will find this useful Physics and optics instructors looking for a reliable teaching tool. Students conducting laboratory work in optics and wave phenomena. Hobbyists and demonstrators who need a compact, stable prism for experiments and displays. Included Triple triangular prism made of optical glass Stable tabletop stand for mounting Notes For results, use a collimated or well focused white light source and a darkened projection surface to observe the spectrum clearly. Handle the optical glass with care to avoid scratches and fingerprints that can affect optical performance.
