Significant Suppliers and Customers | 15. Significant Suppliers and Customers We utilize a number of glass compositions for the manufacture of our molded glass aspheres and lens array products. We purchase glass from Hikari, Ohara, CDGM and other suppliers. Base optical materials, used in both GRADIUM and collimator products, are manufactured and supplied by a number of major optical and glass manufacturers. Optical fiber and collimator housings are manufactured and supplied by a number of major manufacturers. We currently purchase a few key materials from single or limited sources. The polarizing glass used in our isolator products is supplied by Corning USA and Hoya. Garnet and other crystals used in our isolator products are provided by Integrated Photonics. In fiscal 2012 sales to four customers individually comprised at least 5% of our annual sales, with sales to Crimson Trace at 10%, sales to AMS Technologies AG at 9%, sales to Thorlabs at 9% and sales to Raytheon Missile Systems at 5%. The loss of any of these customers, or a significant reduction in sales to any such customer, would adversely affect our revenues. In fiscal 2011, sales to three customers individually comprised at least 5% of our annual sales, with sales to Thorlabs at 9%, sales to Crimson Trace at 7%, and sales to Edmunds Industrial Optics at 6%. The loss of any of these customers, or a significant reduction in sales to any such customer, may adversely affect our revenues.
