K9 Optical Crystal Photography Prism 4piece Set A complete set of optical elements for creative photography and physics demonstration. Each piece is precision cut from K9 optical crystal or optical glass to deliver clear refraction, reliable dispersion, and consistent visual effects. Key benefits Add controlled light effects to photos by creating rainbows, flares, reflections, and creative distortions without digital editing. Demonstrate core optics principles in classrooms or labs with durable, easytoobserve geometry for refraction, dispersion, total internal reflection, and image inversion. Compact, readytouse pieces that fit handheld setups, mounts, or small studio rigs so you can experiment quickly and consistently. What is included 50 mm crystal cube made from K9 optical crystal 50 mm glass triangular prism 55 mm crystal ball made from K9 optical crystal 60 mm optical pyramid made from K9 optical crystal Key attributes Material: K9 optical crystal and optical glass for good transparency and consistent optical behavior Sizes: 50 mm cube, 50 mm triangular prism, 55 mm ball, 60 mm pyramid Function: refract, reflect, disperse, and manipulate light for creative and educational applications Compatibility: works with cameras, lenses, smartphones, lights, tripods, and clamps for both studio and field use Finish: precisioncut faces for predictable light paths and repeatable results How it solves common problems Eliminates the need for complex digital postprocessing by creating incamera effects Provides clear, handson demonstrations of optics concepts that are easier to see than with small or lowquality prisms Offers multiple shapes in one kit so users can test different effects without buying separate accessories Practical use scenarios Portrait and creative photography: Hold or mount a prism or crystal ball near the lens to introduce controlled flare, foreground reflections, or softfocus elements while keeping the subject sharp. Product and still life photography: Position the pyramid or cube to create mirrored patterns and color separation that enhance textures and highlight product details. Physics teaching and demonstrations: Use the triangular prism to show light dispersion into spectrum bands, and use the cube and ball to demonstrate refraction angles and image inversion in classroom experiments. Handling and care Clean with a soft microfiber cloth and mild lens cleaner or distilled water to avoid scratches Handle by the edges to minimize fingerprints on optical faces Store in a padded case or wrapped cloth to protect edges and facets during transport Suitable users Photographers exploring incamera effects and creative lighting Educators and students studying geometric optics and light behavior Content creators and hobbyists seeking physical tools to expand visual possibilities This 4piece optical set provides a practical, durable collection of prisms and crystal shapes for both photographic creativity and handson optics learning.
