Kyropoulos Sapphire Growth

Our highly automated ES2 Growth process is closely monitored by our crystal growth experts to provide consistent high quality and yield. The result is superior quality sapphire with
  • The industry’s lowest etch pit, or dislocation, density (EPD)\
  • High crystal purity (99.996%)
  • Excellent transmission in the UV through IR wavelengths
  • Best crystalline uniformity (by x-ray rocking curve method)
  • Leading refractive index homogeneity
  • Greater uniformity compared with competing sapphire technologies, especially as size scales
Three different sizes of crystals are grown in US:
  • 35 kg for up to 6” parts
  • 85 kg, for up to 11” parts 
  • 200kg for up to 13.5” parts
