Extra large crystals
Monocrystal launched “Extra Large Stress Free” initiative, which resulted in the world’s first 300 and 350 kg KY sapphire crystals. It allowed Monocrystal to bring 300 x 300 mm windows to the market at scale.
Working closely with our partners, we have already enabled several promising large-size applications. We have successfully achieved low stress and 100% clear aperture, crucial for ultra-large sapphire products.
Another objective of the roadmap is to move Monocrystal’s sapphire supply reliability to a new level, which is now of paramount importance, since major LED makers are increasing their capacities.
We are confident that our sapphire extra large windows will allow greater flexibility of our customers’ designs and further expand the scope of sapphire use.
