K9 Optical Glass Crystal Triangular Prism 15 cm Clear, durable triangular prism for teaching, photography, and handson light experiments. Made from K9 optical glass crystal to deliver accurate light dispersion and bright, well defined color spectra. Key benefits Visualizes how white light separates into a spectrum, making abstract optics concepts easy to understand. optical clarity and polished faces reduce distortion for clean, consistent rainbows. Compact 15 cm length fits classroom demonstrations, tabletop photo setups, and science fair displays. Versatile for both education and creative work: useful for physics lessons, STEM activities, and photographic effects. Simple to use and position with common light sources such as sunlight, LED lights, and flashlights. Features and specifications Material: K9 optical glass crystal for strong optical transmission and minimal internal defects. Shape: Equilateral triangular prism designed for predictable refraction and dispersion. Size: 15 cm length suitable for handheld demonstrations and studio setups. Function: Refracts and disperses light to produce visible color spectra and prism effects. Performance: Produces clear, vivid rainbows when used with a focused light beam or natural sunlight. Practical use scenarios Classroom demonstration: Place the prism in a sunlight or flashlight beam to demonstrate refraction, dispersion, and the visible light spectrum during physics lessons. Creative photography: Use the prism near a camera or smartphone lens to create rainbow flares, color reflections, and creative light effects for portraits, product photography, or still life. Handson STEM activity: Let students experiment with angle, distance, and light source to explore how prism orientation affects spectrum position and intensity. Why choose this prism Designed for reliable, repeatable results in both educational and creative settings. Large enough for clear demonstrations yet small enough for easy handling and transport. Compatible with common lighting and imaging equipment for flexible use. Typical users Science teachers and instructors Photography enthusiasts and studio photographers Students and STEM program coordinators Hobbyists exploring optics and light behavior Technical summary Material: K9 optical glass crystal Shape: Triangular prism Length: 15 cm Primary applications: Teaching, rainbow photography, physics experiments, children's light experiments This triangular prism provides a practical, easy to use tool for exploring light and color while supporting educational and creative projects.
