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.
Features
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
