15 cm Triangular K9 Optical Glass Prism for Teaching and Demonstrations A precision triangular prism made from K9 optical glass, designed to split white light into a clear refracted spectrum. Ideal for classroom demonstrations, handson science projects, and creative photography effects. Solid construction and optical clarity make this prism a practical tool for students and instructors. Key benefits Demonstrates light dispersion clearly: separates white light into visible spectrum colors for straightforward visualization of refraction and wavelength. Opticalgrade material: K9 glass offers transparency and consistent light transmission for accurate, repeatable demonstrations. Classroomready size: 15 cm length provides a large, easily visible spectrum during group lessons and presentations. Durable geometric design: triangular prism shape produces predictable refraction angles, simplifying experiment setup and explanation. Easy to use: works with common light sources such as sunlight, LED lamps, and flashlights to produce immediate spectral effects. Important attributes Function: refracts and disperses light to produce a rainbow spectrum for physics teaching and optical experiments. Material: K9 optical glass for clear imaging and minimal internal defects. Size: 15 cm prism length suitable for visible demonstrations and display. Compatibility: designed for use with standard classroom light sources and optical benches or mounts when needed. Performance: delivers distinct color separation and stable refracted beams for observation and measurement. Practical applications Physics classrooms: demonstrate principles of refraction, dispersion, and wavelength with a visible spectrum that students can observe and measure. Home science projects and workshops: use with a flashlight or sunlight to explore color separation, angle dependence, and optical properties. Creative photography and art: introduce controlled rainbow effects into still images or installations by positioning a light source and the prism to cast colored bands. Care and handling Handle with care to avoid chips or scratches on the optical surfaces. Clean gently using a soft microfiber cloth and mild lens cleaner if . Store in a padded box or wrap to protect edges and maintain optical quality. This 15 cm K9 triangular prism is a practical, easytouse tool for educators, students, and hobbyists who need a reliable way to demonstrate and explore light dispersion and basic optical principles.
