Customized Sapphire Tube Optical Components

What is Sapphire tube？

The Sapphire tube is a components made from single-crystal aluminum oxide (Al₂O₃).

With its well mechanical strength, thermal stability, and chemical resistance, people often use the tube in laser systems.

Compared with the conventional glass or quartz tubes, it offers superior hardness (Mohs 9), high transmission from UV to IR, and outstanding durability in extreme conditions.

The sapphire tube can withstand inside pressure exceeding 100 MPa.

Key Advantages of Sapphire Tubes

• Exceptional Hardness & Scratch Resistance

The hardness of the sapphire tube is only lower than the diamound. It ensures long service life even in abrasive or high-pressure environments.

• Wide Transmission Range

Sapphire offers high optical transmission from 190 nm (UV) to 5 μm (mid-IR). Therefore, people often use the tube in laser systems.

• Thermal Stability

The Sapphire tube maintains mechanical strength and optical clarity in temperatures up to 1,900°C in air and 2,000°C in inert atmospheres.

It is ideal for high-temperature furnaces and optical measurement systems.

•  Chemical & Corrosion Resistance

Resistant to most acids, alkalis, and corrosive gases, sapphire tubes are suitable for harsh chemical environments.

• Dimensional Precision

You will not be worry about if it is matched with the optics because it ensures precise fit and reliable sealing in high-precision assemblies.

Applications of Sapphire Tubes

• Laser Systems

People often use it as protective windows or beam delivery components for high-power lasers.

• Medical Devices

Some tools like endoscopic tools, fluid delivery systems, and sterilization are also needed the tube.

• Semiconductor Industry

The sapphire tube can also be used as tube liners for wafer processing equipment.

• Harsh Environment Sensing

Some harsh environments can also use it well. Temperature and pressure sensors in extreme industrial conditions.

• Aerospace & Defense

High-strength optical housings and protective sleeves.

• Spectroscopy & Analytical Instruments

In UV/IR environment, people can also choose it as transparent sample holders.
