Product Details
Dia 2inch Synthetic Sapphire Rod
Properties of Sapphire Rod
Optical Windows are used as viewports to protect other components
within an optical assembly, instrument, or laser. In certain
applications, optical windows are required to withstand harsh
environmental conditions and provide high levels of performance and
reliability. Sapphire window has several unique properties that
make it the ideal material for these applications.
Description
Sapphire is a single crystal aluminum oxide (Al2O3). It is one of
the hardest materials. Sapphire has good transmission
characteristics over the visible, and near IR spectrum. It exhibits
high mechanical strength, chemical resistance, thermal conductivity
and thermal stability. It is often used as window materials in
specific field such as space technology where scratch or high
temperature resistance is required

Company Profile
Chongqing Silian Optoelectronics Science & Technology Co., Ltd was
founded by China Silian Instrument Group Co., Ltd for the
development of LED industry. After the acquisition of Honeywell
Sapphire business, the company has become China’s first enterprise
with the world’s top-quality large-sized sapphire production and
R&D capabilities. The company has the world’s leading
high-power sapphire substrates technology. Taking the excellent
oppotunity, the company has developed LED packaging, LED lighting
applications and other industries in succession to project
extension in LED industrial chain. Based on the core-technology of
sapphire substrates, we have created an area of 1000 mu
(approximately 66.7 hectares) to develop LED industrial china from
basic materials to high end products and become the most completed
and largest semiconductor energy-efficient in dustrial base in
Western China.
Maintaining the enterprise spirit of “People oriented, Natural
Selection, Inheriting innovation and Pursuit of Excellence” and the
customer tenet of “Silian is guided through customers and stands
with customers”, we are committed to provide customers with
high-quality sapphire chip substrates, optical window materials,
LED packaging devices, and high efficiency LED lighting desplay
high end products and creating value for customers.
Silian the international large-sized sapphire substrates standards
lauching member.
Acquiring the completed production line from sapphire crystal
growth to substrate processing.
We have the qulity advantages of high purity, high consistency and
high repeatability.
Cooperating with world top level LED chip manufactures.
