Sapphire and optical device

the first manufactory in China with capability of growing, processing large size sapphire ingot with top quality and processing capacity with an annual of 10000 / piece infrared optics.



After the successful introduction of Kyropoulos technology from Russian in 2010, through the digestionSapphire and absorption of sapphire growth and processing technology, our production capacity is promoted to a year yield 1000 sapphire crystal ingot.

Our ingot specifications has covered 30kg,60kg,85kg,90 kg, wafer specifications has covered 2inch, 4inch, 6inch, 8inch, 10-inch. We formed sapphire business as the core, LED packaging as a link, LED applications to support the industrial layout. Our company is mainly dedicated to large-size infrared transparent material and sapphire devices R & D, production, sales and technical consultation, our products covered Φ50-Φ250 dome,Φ50-Φ250 plane lens and 50 *50-360 * 260 windows etc.

Our company is engaged in the sapphire growth, processing and optical instruments and devices processing for over 50 years, we have professional technical talents, mastered the core technology of sapphire and optical device production and processing with perfect production technology, we can provide customers with a large number of long-term, stable sapphire and other optical products.

The manufactory promoted the ISO9001 and TS16949 Quality System construction actively, insists on continuous improvement, constantly optimizes the quality management, continue to improve products quality, we always obtains consistent highly praise from different customers.
