Clear cast acrylic cabochons - solid half-domes with flat backs and mirror-polished convex surfaces - in diameters from ⅜″ up to 3″. Sizes: ⅜″, ½″, ⅝″, ¾″, 1″, and up to 3″. Optical-grade cast acrylic at 92% light transmission and refractive index ~1.49, void-free, with a precision-polished dome that focuses and refracts light cleanly. Sold individually and in volume packs.
Used in jewelry and epoxy resin art as dome covers, badge inserts, and pendant elements. Applied to signage as embellishments and focal points. Used in optical demonstration for light-focusing and magnification experiments. Incorporated into furniture and fixture fabrication as CNC-cut accent pieces. Used in photography for lens effects and macro prop work. Solvent-bonds cleanly to acrylic substrates. Bulk options 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.
