Our Clear Cast Acrylic Sphere Collection combines flawless optical clarity with precision craftsmanship—ideal for everything from decorative design to technical and educational use.
Made from premium cast acrylic (PMMA), these spheres deliver ~92% light transmission, refractive index ≈ 1.49. With available sizes from ¼″ up to 4″ diameter, including our rarely offered 4″ spheres, this collection stands out as one of the most comprehensive in the industry.
Optical-Grade Cast Acrylic: Crystal-clear, distortion-free finish
Expanded Size Range: From ¼″ to 4″, including the hard-to-find 4″ diameter
Durable & Lightweight: Half the weight of glass, yet impact-resistant
Mirror-Polished Finish: Smooth, glossy surface for maximum clarity
UV & Scratch Resistance: Maintains brilliance indoors and outdoors
Our spheres are used across creative, scientific, and professional fields:
Retail & Displays: Accent pieces, showpieces, signage décor
Photography & Film: Light refraction props, visual effects, set design
Educational & Lab Use: STEM demonstrations, optical refraction studies, geometry models
Prototyping & Engineering: Calibration spheres, precision modeling, mechanical testing
Art & Sculpture: Standalone art objects, installations, and mixed media designs
While most suppliers cap at 3″ diameters, we proudly stock 4″ clear cast acrylic spheres—an exclusive size few competitors carry. Combined with our optical-grade polish and tight tolerances, these spheres are trusted by designers, educators, and engineers who demand both beauty and precision.
