Clear acrylic spheres in diameters from ¼″ up to 4″, including the 4″ size that most suppliers don’t stock. Mirror-polished finish throughout - smooth, distortion-free, optically clear at 92% light transmission and refractive index ~1.49. Cast acrylic, not extruded - superior surface quality.
Used in retail displays and visual merchandising as accent and showpiece elements. Used in photography and film for light refraction effects, visual props, and set design. Used in STEM education for optical refraction demonstrations and geometry models. Used in engineering and prototyping as calibration spheres and precision modeling components. Used in sculpture and mixed-media art installations.Volume packs and custom bundles available. Contact us via our custom order form.

QUALITY GUARANTEED
Cast acrylic blocks, cubes, spheres, and cabochons - optical-grade material at 92%+ light transmission and a refractive index of 1.49, polished to a glass-like finish. Four shapes, multiple size ranges, clear and colored options. In stock at 345 Canal Street and available for same-day pickup, bulk orders, and custom fabrication.
Cubes and blocks are used as display risers, award bases, signage bases, architectural models, and precision-machined components for engineering and prototyping. Cabochons - polished half-domes with flat backs - are used in jewelry, resin art, signage lenses, and optical demonstration. Spheres run from ¼″ up to 4″ diameter, including the rare 4″ size, and are used across retail displays, STEM education, optics work, sculpture, and photography props. Colored spheres in amber orange, blue, green, pink, purple, and red transparent are in stock alongside clear.
All shapes are cast acrylic - superior optical clarity and dimensional stability compared to extruded. Fabrication services available in-house: cut to size, edge polishing, UV printing, cementing, and drilled holes. Bulk pricing available for quantity orders - Contact us via our custom order form.
