Product Introduction Of Sapphire Tubes
sapphire tubes are produced using advanced growth technologies that
result in high-purity, optically uniform single crystals. These
tubes are free of growth striations or visible internal defects,
making them ideal for demanding applications in optics, photonics,
and medical instrumentation. They offer excellent transparency
across visible to mid-infrared wavelengths.
Working Principle Of Sapphire Tubes
To avoid striations, sophisticated control over thermal gradients,
pulling speed, and impurity concentration is required during
crystal growth. Advanced techniques such as modified KY, horizontal
directional solidification, or EFG are used. Slow growth and
post-annealing ensure refractive index uniformity and high optical
quality.
Applications Of Sapphire Tubes
Industrial Inspection Windows: Transparent windows for
high-temperature furnaces or plasma chambers.
Optical Fiber Sheathing: Protection of sensitive optical/fiber
components in harsh environments.
High-Temperature Sensor Housing: Enclosure for thermocouples or
optical temperature sensors.
Medical Devices: Fluid delivery systems or probe housings in
high-sterility environments.
Military & Aerospace: Windows and monitoring tubes for missiles or
spacecraft.
Q&A Of Sapphire Tubes
Q1: What is the maximum temperature a sapphire tube can withstand?
A1: Sapphire tubes can withstand up to 1600°C in air and over
2000°C in inert or vacuum environments.
Q2: Is sapphire electrically conductive?
A2: No, sapphire is an excellent electrical insulator, suitable for
high-voltage applications.
Q3: Is it suitable for vacuum or pressure environments?
Yes. Sapphire’s excellent hermeticity and mechanical strength make
it ideal for such applications.
Q4: Can AR coating or anti-reflective treatment be applied?
Yes. Multi-layer AR coatings can be customized to enhance optical
performance.
