Rubicon Technology, Inc. (NASDAQ:RBCN), a leading provider of sapphire substrates and products to the LED, semiconductor, and optical markets, today announced that it will display its line of optical products for use in defense and aerospace, instrumentation and analytical processing, sensors and detectors, semiconductor process equipment, and medical and laser applications at SPIE Optifab, October 15-17, 2013, at the Rochester Riverside Convention Center in Rochester, New York. Rubicon will show the company’s optical-grade sapphire products including sapphire plates, windows, domes, and tubes in booth #1206. In addition, the company will exhibit sapphire ingots in 4-inch through 12-inch diameters. Sapphire, the second hardest material in nature after the diamond, delivers advantages for optical applications due to its unique hardness and strength, chemical inertness, and transparency in the visible and IR spectrum. The use of sapphire results in better performance, yield and cost than alternatives. “Sapphire presents a unique opportunity for optical fabrication for applications that require extreme durability and scratch resistance,” said Raja M. Parvez, President and CEO, Rubicon Technology. “Rubicon’s proprietary crystal growth technology produces high quality sapphire in various sizes and crystal orientations in high production volumes. Using sapphire for optical applications can help companies fabricating optical products achieve their objectives for product performance, yield and total cost.” Rubicon will have a number of optical sapphire products of different sizes and orientations on display in booth #1206 at SPIE Optifab including sapphire plates, windows, domes, tubes, and ingots ranging from 4 to 12 inches in diameter.
