Detail Information

Sapphire Optical Cube | Custom Sapphire Block for Optical Systems

Sapphire optical cubes (also known as sapphire blocks or prisms) are precision-machined single-crystal sapphire components with multi-sided optical-grade polishing. These cubes feature exceptional hardness, wide spectral transmission and excellent thermal stability, making them ideal for use in optical systems, laser equipment, laboratory instruments and industrial applications.

Core Advantages

  • Mohs 9 ultra-high hardness, excellent scratch and wear resistance
  • Ultra-wide transmission range from 150nm UV to 5.5μm mid-infrared
  • Six-side optical-grade polished finish with high parallelism and flatness
  • Excellent thermal stability and high-temperature resistance
  • High chemical resistance against acid, alkali and corrosive environments
  • Customizable dimensions, tolerances and surface quality
  • Strict dimensional accuracy control for precision optical assembly

Available Types & Sizes

  • Standard sapphire cubes with equal side lengths
  • Custom rectangular sapphire blocks
  • Sapphire prism blocks with specific angles and cuts
  • Special-shaped sapphire optical blocks per customer drawings
