Rubicon Technology Shows Off Sapphire Optical Products At SPIE Defense, Security, And Sensing Conference

Rubicon Technology, Inc. (NASDAQ:RBCN), a leading provider of sapphire substrates and products to the LED, RFIC, semiconductor, and optical industries, today announced that it will be showing its line of sapphire optical products including sapphire ingots, windows and blanks at the SPIE Defense, Security, and Sensing conference in Baltimore, MD, April 23 – 27, 2012 in booth #545.

Sapphire is ideal for high-performance optical applications because of its physical properties such as optical transparency, physical strength, resistance to abrasion and corrosion, temperature durability, and bio-compatibility.

“Rubicon’s ES2 crystal growth method has been refined over the past 11 years to provide consistently high yield and the highest quality sapphire for our customers,” said Raja Parvez, president and CEO of Rubicon Technology. “With this expertise, Rubicon has been able to scale the growth of bulk crystal up to 200 kg without compromising high quality or high yield. This enables us to produce industry-leading, very large, defect-free sapphire crystal for use in the optical market for a wide range of industrial applications.”

Rubicon provides sapphire products in 4-inch, 6-inch and 8-inch diameters and will be exhibiting a 12-inch sapphire window. Rubicon will display its line of optical products including very large size sapphire windows and blanks for use in Defense and Aerospace, Instrumentation and Analytical Processing, Sensors and Detectors, Semiconductor Process Equipment, and Medical and Laser applications.

Defense & Aerospace -- Sapphire is used in the defense and aerospace industries due to its broad transmission range in the UV through IR spectrum, resistance to scratching and corrosion in sand or salt environments and impact resistance. Applications include targeting systems and protected optics for fighter jets, UAVs and helicopters, FLIRs and Enhanced Vision Systems for aircraft, sensor suites and shaped optics for land, air and sea vehicles, missile domes, countermeasure lamps and transparent armor systems.

Instrumentation & Analytical Processing -- Sapphire often replaces quartz and glass to provide longer life in equipment and consumables. Sapphire's chemical resistance, ability to withstand high temperature and high pressure, and ability to transmit in UV and IR ranges make it ideal for applications in instrumentation and analytical processing such as mass spectrometry, spectrophotometry, digestive cells, and other analytical applications.

Sensors & Detectors – Sapphire’s UV and IR transmission properties-- in combination with its ability to withstand harsh chemicals, high pressures and temperatures--offer strong advantages for fire and IR detectors, protective windows and thermocouple protection sheaths for remote sensors, and optics for harsh environments such as oil-well drilling, chemical processing and other industrial processes.

Semiconductor Process Equipment -- Sapphire’s durability and resistance to fluorine chemistries and high-temperature process environments up to 2,000°C offer advantages over materials such as quartz, alumina and other ceramics for semiconductor process equipment. Sapphire often replaces these materials in process chamber environments.

Medical & Laser -- Sapphire's optical transmission range, durability, ability to be shaped into sharp-edged products and inertness with human tissue offer advantages for specific medical laser applications for dermatology, ophthalmology and dentistry. Sapphire products are also used for surgical tools, implants, braces and in a variety of windows for medical equipment such as endoscopes and lasers.
