Compact, precision optical prism designed for handson experiments, demonstrations, and creative light effects. This triple triangular prism refractor is made from K9 crystal optical glass and sized 3x3x3x15cm for stable handling and consistent results. Key benefits Clear demonstration of refraction and dispersion: precise triangular geometry and polished faces produce distinct light bending and color separation for educational experiments and visual demonstrations. Durable optical material: K9 crystal optical glass offers transparency and uniformity for repeatable, lowdistortion performance. Versatile and easy to use: the compact 3x3x3x15cm format fits standard lab setups and handheld demonstrations while offering a long optical path for stronger effects. Consistent geometry for predictable results: accurately cut faces and angles reduce experimental variability and make data collection more reliable for classroom and lab work. Main features and attributes Function: triple triangular prism refractor for splitting, refracting, and redirecting light; suitable for studying refraction, dispersion, total internal reflection, and angular deviation. Material: K9 crystal optical glass with polished optical faces for clear transmission and color separation. Size: 3x3x3x15cm providing a compact footprint with an extended length to enhance observable effects. Performance: stable optical behavior under visible light with clean, repeatable refraction patterns; suitable for white light and narrowband light sources. Compatibility and handling Compatible with standard physics lab equipment and optical benches as a demonstration or experimental element. Works well with LED light sources, lasers for alignment demonstrations, cameras for creative imaging effects, and classroom projectors. Handle by edges and store in a padded case to maintain optical surface quality; clean with appropriate optical tissue and solvent when required. Practical applications and scenarios Classroom physics lab: use the prism to demonstrate light refraction, dispersion into constituent colors, and the principles of angle of incidence and refraction for students. Photography and videography: mount or handhold the prism to create streaks, color separation, and kaleidoscopic effects in creative shoots. Science demonstrations and exhibits: incorporate the prism in handson displays to visualize internal reflection and color splitting in a clear and engaging way. What makes this prism stand out Triple triangular design and 15cm length deliver stronger, more visible dispersion and refraction compared to shorter single prisms. K9 optical glass and precision cutting produce stable, lowdistortion optical performance suitable for both educational and creative uses.
