About Sapphire
Sapphire is the general name for corundum gemstones other than
ruby, and its main component is aluminium oxide (Al2O₃). Sapphire
can be pink, yellow, green, white, and even in the same stone. The
blue sapphire is due to the presence of a small amount of titanium
(Ti) and iron (Fe) impurities.
The biggest feature of sapphire is uneven colour. You can see
straight colour bands and growth lines of different depths arranged
in parallel hexagonal prisms. Polysynthetic twins are developed,
and shutter-type twin patterns are common. Cracks are mostly split
along twin planes. Strong dichroism.

About Sapphire Optical
Sapphire optical cylinders, with diameters typically ranging from a
few millimetres to several centimeters and customizable lengths,
are highly valued for their superior optical performance and
durability.
These properties make them ideal for use in lenses, windows, sensor
covers, and diffuse filters.
Their excellent thermal stability and chemical resistance also make
them suitable for high-temperature applications and medical
devices, where biocompatibility and sterilization resistance are
crucial.
In addition to these uses, sapphire optical cylinders are widely
employed in infrared and far-infrared military equipment, including
night vision infrared and far-infrared sights, and night vision
cameras.
They are also integral to satellite and space technology
instruments, high-power laser windows, various optical prisms,
optical windows, UV and IR windows and lenses, and observation
ports for low-temperature experiments.
The combination of these versatile properties makes sapphire
optical cylinders a reliable choice for a broad spectrum of
industrial, scientific, and medical applications.
