120kg High quality sapphire ingot

Product Description

Focusing cones (focones) also belong to light guide facilities. By means of sapphire focones the emission of high-power xenon lamps is transformed into a point or linear source (“light knife”). For the latter transformation the shape of the input face is calculated, allowing redistribution of incident light flux in the required way .

To raise the photoresistance of focones to high-power UV radiation, the crystals are saturated with anionic vacancies. In the course of long-term operation of the crystal, induced absorption may arise and the temperature of the output face will decrease. Annealing under reducing conditions completely restores the optical quality of the article. 

Zhongju has break through the limitations of traditional crystals growth by Kyropoulos method, which is difficult to grow high-quality, large-size sapphire crystals. Currently 120kg high-quality sapphire crystals are produced stably, and the production capacity can satisfy the requirement of reliable supply. We have the ability to produce much larger crystal, if customer has corresponding request. The maximum diameter of substrate or components could reach up to 12 inches.
