Sapphire Optical Fiber Introduction
Custom Sapphire Optical Fiber Diameter 100μm for Environmental Sensors
Sapphire optical fiber is a material renowned for its exceptional chemical corrosion resistance and a melting point of 2,072°C. ZMSH offers LHPG (Laser Heated Pedestal Growth) grade sapphire fibers with diameters ranging from 75 to 500 μm. Furthermore, fibers with enlarged ends, fabricated through tapering processes, are also available. This is a significant feature because the flexibility of the fiber varies inversely with the fourth power of its diameter (e.g., a 100 μm fiber is 16 times more flexible than a 200 μm fiber). Tapered fibers provide users with high light transmission capability without sacrificing flexibility, making them suitable for both energy transmission and spectroscopic applications. PTFE sheaths and/or connectors are available for fibers with diameters larger than 100 μm.
Sapphire Optical Fiber Features
The core advantages of sapphire fiber lie in its stability and reliability under demanding conditions.
- Exceptional Heat Resistance: With a melting point of 2072°C, it can operate stably in high-temperature environments for extended periods, a capability unmatched by conventional glass fibers.
- Outstanding Mechanical Strength: Sapphire fiber exhibits extreme hardness and high tensile strength (approximately 2200 MPa), along with stable chemical properties that resist corrosion and wear.
- Excellent Optical Properties: It maintains high transmission efficiency across a broad wavelength range from visible light to mid-infrared (e.g., 5 μm), and possesses a high laser damage threshold, making it suitable for transmitting high-power lasers.
Sapphire Fiber Main Application Fields
Leveraging these characteristics, sapphire fiber is indispensable in several high-end fields.
- Sensing and Monitoring in High-Temperature Environments: Examples include high-precision temperature measurement inside aerospace engines, gas turbines, and industrial furnaces.
- High-Power Laser Transmission: Used for reliable transmission of high-energy lasers in medical applications (e.g., dentistry, surgery), industrial processing, and scientific research.
- Communication and Signal Transmission in Special Environments: Enables stable optical signal transmission in complex industrial settings with strong electromagnetic interference, high radiation, or highly corrosive chemicals.
