Clear cast acrylic blocks in sizes from 2″×2″×1″ up to 4″×4″×10″. Cut from solid cast acrylic and finished with diamond polishing and hand buffing - sharp corners, sharp edges, high gloss throughout. Optical-grade clarity at 92% light transmission and a refractive index of 1.49. Lighter than glass, dimensionally stable, and machines without stress-crazing.
Used as display risers and bases in retail, galleries, and museums. Engraved for awards, trophies, and architectural signage. Machined and CNC-milled for precision prototyping and custom fabricated components. Used in architectural scale models, photography props, and educational optical demonstrations. White and black blocks available up to 1″ thick. Clear blocks available in special order up to 6″ thick - contact us via the custom order form.
Fabrication available in-house: cut to size, edge polishing, UV printing, cementing, and drilled holes.

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.
