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.

FAQ
1. Q: What are the advantages of using sapphire optical cylinders compared to other materials?
A: Due to their high hardness, excellent optical clarity and chemical and thermal resistance, sapphire cylinder lenses can cope with harsh working environments.
2. Q: Are sapphire optical cylinders suitable for everyday use?
A: Though they are very highly durable and resistant to damage, their high cost may not justify their use for everyday applications.
Besides, they are more often to be used in high-precision optics, medical devices, and luxury watches.
