We continue to talk with other potential customers in the Asia region for our sapphire crystallization systems and believe we are on track to meet our projected $100 million in revenue in our FY12 from sapphire crystallization equipment sales.” The two orders represent GT Solar’s entry into the LED equipment market, which GT Solar stated it would pursue when it announced its acquisition of Crystal Systems in July of 2010. Both Jiangsu Jixing New Material Co., Ltd and Jiujiang Sapphire Tech Co., Ltd are positioning themselves to capitalize on the expected growth of the LED market over the coming years by building the capacity to produce high quality, large area sapphire substrates.
