Surface Roughness Ra 0.2nm Sapphire Wafer - Perfect for demanding
applications
Product Description:
Sapphire Wafer is a kind of sapphire plate made from high quality
sapphire substrate, which is a special kind of sapphire slice cut
from high purity single crystal sapphire ingots. It is widely used
in the fields of optoelectronics, semiconductor, precision optics,
etc. Our sapphire wafer has excellent physical characteristics,
such as high hardness, good thermal stability, good heat conduction
and high light transmittance. Moreover, its thickness ranges from
0.5mm to 3mm, its shape is wafer, its clear aperture is over 90%,
its perpendicularity is less than 3 Arc Min and its diameter is
from 2inch to 8inch.
