1. Description For Sapphire
Sapphire is made from 99.999％ Al2O3 and is one of the hardest
materials, it possesses
very good transmission during the range ofvisible and near IR
spectrum. so it is widely used
as optical window in infrared and far infrared military equipments,
apparatus and instruments
of satellite and space technology, and navigation and spaceflight,
such as night infrared scope
sight and night vision camera, etc.
The wavelength of worldhawk general windows substrate(without
coating)

ZMKJ we locate in the city of Shanghai, Which is the best city of
China, and our factory is
founded in Wuxi city in 2014.We specialize in processing a varity of materials into wafers,
substrates and custiomized optical glass parts.components widely
used in electronics,
optics, optoelectronics andmany other fields.
We also have been working closely with many domestic and oversea
universities, research
institutions and companies, provide customized products and
services for their R&D projects.
About sapphire,so we can supply professional customized service in
time and provide cooperation
and support of newproduct development and technology appliance.
