SAPPHIRE WINDOWS, WAFERS AND SHIELDS MANUFACTURER

Rayotek is a premier wafer, shield & precision sapphire optical windows manufacturer. Because of sapphire's durability and scratch resistance, it is far superior to any type of glass for window, wafer, optical and shield applications.

In addition, sapphire transmits more into the infrared and ultraviolet range than most glasses. Sapphire is also more temperature and chemical resistant than any other transparent (and most non-transparent) materials.

Rayotek grows, machines, grinds and polishes:

  • Sapphire shields & blanks
  • Sapphire sheet & flat stock
  • Sapphire semiconductor wafers
  • Sapphire safety & blast shields
  • Sapphire optical windows for camera & imaging protection
  • Sapphire windows for semiconductor plasma & chemical etching applications
  • Scratch & impact resistant sapphire scanner windows, PDA windows & display windows
  • Sapphire windows for furnace, pyrometer & other high temperature application

 


 
       

Sapphire optical windows are ideal for window applications requiring:

  • Highest strength of all optical window materials except diamond
  • Most chemically durable optical window material available
  • Chemical resistance to virtually all chemicals except some molten salts and boiling concentrated HF
  • Optically transparent from 200nm to 6µm
  • High dielectric constant with low loss tangent
  • Highest melting point of all readily available optical window materials
  • Resistant to solarization (UV radiation darkening)
