Description of Sapphire Optical Tubes
The sapphire tube is a high-performance material pipe made of single-crystal sapphire with excellent physical and chemical properties.
Sapphire (aluminium oxide single crystal) has extremely high hardness, second only to diamond, and has strong wear resistance and scratch resistance.
It is widely used in fields that require high durability.
Sapphire tubes also have excellent high-temperature and chemical corrosion resistance and can maintain stability in extreme environments.
This makes sapphire tubes important in high-temperature equipment, optical instruments, medical equipment and other fields.
In addition, the high light transmittance of sapphire makes it excellent in optical applications, especially in the ultraviolet and infrared ranges and can transmit light of specific wavelengths without being affected.
Sapphire tubes are also widely used in precision manufacturing, aerospace, and semiconductor industries, and are indispensable key components in many high-tech fields.

FAQ
1. Q: How do you produce sapphire tubes?
A: We use Ky method and EFG method to manufacture, while different methods are suitable for different environments.
2. Q: Compared with the quartz tubes, what is the advantage of sapphire?
A: Compared with quartz tubes, sapphire tubes are much harder, much better performance and they can be used in harsh situations due to their higher temperature resistance and scratch resistance.
