Product: Triangular Prism model Material: K9 optical glass Dimensions: triangle sides 3 cm, overall length 5 cm Surface quality: 40/20 Quantity: 1 pc triangular prism Key benefits Precise light control for teaching and testing: the K9 optical glass and accurate geometry produce clear refraction and dispersion, making the prism suitable for classroom demonstrations and lab experiments. optical clarity for photography: surface quality reduces stray scattering and preserves image detail when used in creative or commercial photography. Versatile and compact: the 3 cm by 3 cm triangular cross section with a 5 cm length balances portability with stable handling for a variety of setups. What makes it stand out K9 optical glass construction provides consistent optical performance for experiments and imaging. Surface quality rated 40/20 ensures low surface defects and reliable results in precision tasks. Singlepiece triangular design is easy to position and mount in optical benches, clamps, or handheld setups. Functions and compatibility Demonstrates refraction, dispersion, total internal reflection, and beam deviation in physics lessons. Compatible with common optical setups, photography rigs, and educational experiment kits. Works well with lasers, collimated light sources, LED sources, and camera lenses for creative and technical applications. Practical use scenarios Classroom physics demonstration: show white light splitting into a visible spectrum, study angles of refraction, and explore light behavior in a handson lesson. Photography and videography: add spectral effects, color separation, or subtle flares to product shots, portraits, and creative compositions. Laboratory experiments and hobby optics: use for beam steering, simple spectrometry exercises, alignment checks, and light path studies. What is included 1 pc clear triangular prism made of K9 optical glass, triangle side length 3 cm, overall length 5 cm. Care and handling Handle with care to avoid chips or scratches. Clean with a soft lens cloth and appropriate optical cleaning solutions. Store in a padded case or protective wrap to preserve surface quality. This triangular prism is a practical, precise tool for education, photography, and optical experiments where controlled refraction and clarity are required.
