Optical Crystal Mini Prism 20 x 20 x 20 mm Description A compact optical crystal prism designed for hands on optics learning, creative photography, and DIY kaleidoscope projects. The 20 x 20 x 20 mm mini prism delivers clear refraction and internal reflection for reliable visual experiments and visual effects. Key benefits Clear optical performance: Precisioncut crystal surfaces produce distinct refraction and internal reflections for demonstrating light behavior and creating visual effects. Compact and easy to use: Small 20 x 20 x 20 mm size fits classroom kits, craft projects, and handheld demonstrations without added bulk. Durable optical material: Solid crystal construction holds shape and clarity through repeated handling and demonstrations. Versatile application: Works for science lessons, hobby optics, photography effects, and craft assemblies. What it does and why you need it Demonstrates core optics principles such as dispersion, refraction, and total internal reflection in a single, easytohandle component. Replaces fragile or imprecise teaching aids with a compact, repeatable element for experiments and demonstrations. Enhances creative projects by adding controlled light splitting and mirrored reflections to produce rainbows, multiimage patterns, and kaleidoscopic effects. Key attributes Function: Splits and redirects light, demonstrates dispersion and internal reflection, and creates multiimage or spectrum effects. Size: 20 x 20 x 20 mm compact prism suitable for small setups and handheld use. Material: Optical crystal for good transparency and controlled light transmission. Performance: Produces clear spectral separation and consistent reflection paths when aligned with a light source. Use scenarios Classroom optics demonstration: Use with a flashlight or LED to show how white light separates into a spectrum and to illustrate refractive index concepts. DIY kaleidoscope and craft projects: Combine multiple prisms or place inside tube assemblies to create repeating mirror patterns and color effects. Creative photography and videography: Hold the prism in front of a camera lens to introduce controlled flares, reflections, and splitimage compositions for artistic shots. Practical notes Handle with care to avoid scratches on optical surfaces; clean with a soft, lint cloth. Position relative to a light source or lens to achieve desired dispersion or reflection; small adjustments produce noticeable changes in effect. Compatible with standard small optics kits and craft builds that accept 20 mm components. This mini optical prism provides a compact, reliable tool for educational demonstrations, creative applications, and hobbyist optics projects where clear refraction and repeatable results are needed.
