Index matching silicone for optoelectronic applications

Although silicone technology has existed for over 5 decades, this unique material continues to find usage in new applications. Its unique chemical and physical characteristics allow its usage as fuel resistant gaskets, biologically compatible for us in medical devices in the body, coatings for Atomic Oxygen protection in space, and for interocular lenses for cataract disease. This paper will examine various silicones as effective encapsulants and lenses for High Brightness LEDs (HB LEDs). Physical and optical characteristics will be tested to determine which materials may prove to be the best.
