Product Description

YAG optical crystals

Undoped Yttrium Aluminium Garnet (Y3Al5O12 or YAG) is a new substrate and optical material that can be used for both UV and IR optics. It is particularly useful for high-temperature and high-energy applications. The mechanical and chemical stability of YAG is similar to that of Sapphire, but YAG is not birefringent. This particular feature is extremely important for some optical applications.



  • Transmission in 0.25-5.0mm, no absorption in 2-3mm

  • High thermal conductivity, 10 times better than glasses

  • Extremely hard and durable

  • Non-birefringence

  • Stable mechanical and chemical properties

  • High bulk damage threshold

  • High index of refraction, facilitating low aberration lens design


  • Laser igniters
  • Laser-induced breakdown spectroscopy
  • Optical substrates and windos
  • Particle image velocimetry
  • Cavity ring-down spectroscopy
  • Transparent electronic substrates
  • Right angle prism
