1mm High Quality Sapphire Optical Glass Windows

Product Description

The light sources in which light-emitting diodes are used instead of filament lamps allow reduction of electric power consumption by approximately ten times. It has been calculated that the funds that could be saved due to the substitution of conven-tional light sources by light diodes in all the world’s lighting systems would be equivalent to the cost of several hundred nuclear power stations! 


Although there are lots substrates which are regarded as potential materials to replace sapphire substrate, it is still dominated in the substrates (for GaN LED growth) market, because of its reasonable price and relatively low mismatch. Zhongju is capable of processing substrates according to customer needs. Currently, our sapphire substrate productions ranges from 2 to 12 inches with high quality and accurate orientation.
