Sapphire Fiber Description:
Sapphire Fiber is a unique type of optical fiber material made from
single-crystal α-alumina (Al2O3). It exhibits excellent performance
under high temperatures, harsh chemical environments, and high
radiation conditions, making it an ideal choice for various
industrial applications, especially in environments where
conventional optical fibers fall short.
Key features of Sapphire Fiber include:
High-temperature stability: Sapphire Fiber can operate stably for
prolonged periods at temperatures exceeding 2000°C without
compromising its structure or optical properties.
Chemical stability: It is highly resistant to most chemical
substances and corrosive environments.
Mechanical strength: It boasts high tensile and bending strengths.
Broad transparency range: Sapphire Fiber has good transparency
across a wide wavelength range, from ultraviolet to mid-infrared.
High radiation resistance: Suitable for environments with high
radiation, such as nuclear power plants or space applications.
Given these characteristics, Sapphire Fiber holds great potential
in various applications, including high-temperature sensing,
medical imaging, military, and space applications.

chemical corrosion resistance. Therefore, in environments with
strong corrosivity, sapphire fibers can provide reliable data
transmission for sensors.
- Medical applications: Due to its biocompatibility and chemical
stability, sapphire fiber is used in certain medical applications,
such as endoscopes or laser surgeries.
- Laser transmission: The excellent optical properties of sapphire
make it an ideal medium for the transmission of high-power or
specialized wavelength lasers.
- Research applications: In certain high-end research applications,
like nuclear reactors or high-energy physics experiments, sapphire
fibers are chosen for their high radiation resistance and stability
under extreme conditions.
- Optical communication: Although conventional optical communication
primarily uses quartz fibers, sapphire fibers may be selected for
certain special environments or applications.

Sapphire Fiber Advantages:
- Chemical Resistance: Compared to other optical fiber materials,
sapphire exhibits excellent resistance to chemical corrosion,
allowing it to work reliably in harsh chemical environments.
- Biocompatibility: Sapphire fiber is safe for human contact, giving
it an advantage in medical applications.
- Optical Properties: Sapphire fiber offers excellent optical
transparency and low optical losses.
- Radiation Resistance: In radioactive environments, sapphire fiber
experiences significantly less performance degradation compared to
other optical fibers.
- Mechanical Strength: Due to sapphire's hardness, second only to
diamond, sapphire fiber has high compressive and tensile strength.
