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.
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.
