Custom-made fiber optic sensors

Custom fiber optic sensors are widely available and can be tailored for specific applications in industrial, medical, and research environments.

Overview of Custom Fiber Optic Sensors

Custom fiber optic sensors are devices that convert physical phenomena such as temperature, pressure, strain, or vibration into optical signals. They leverage the properties of light traveling through optical fibers, offering high sensitivity, immunity to electromagnetic interference, and durability in harsh environments . These sensors are particularly valuable in applications requiring real-time monitoring, precise measurements, and integration into complex systems.

Materials and Design Options

• Borosilicate fibers: Offer excellent chemical and thermal resistance, suitable for industrial process monitoring, medical instrumentation, and decorative lighting .
• Silica fibers: Provide maximum heat resistance up to 1000°C, ideal for high-power laser delivery, pyrometry, and surgical applications .
• Single-mode or multi-mode fibers: Depending on the application, fibers can be optimized for long-distance signal transmission or high-resolution sensing .

Customization Capabilities

Manufacturers can tailor fiber optic sensors to meet specific operational requirements, including:

• Sensor length, diameter, and geometry
• Integration with existing systems or control networks
• Environmental resistance (temperature, chemical exposure, radiation)
• Distributed sensing along the fiber for continuous monitoring of pipelines, structures, or large areas

Applications

Custom fiber optic sensors are used in a wide range of industries:

• Industrial process monitoring: Inline measurement of temperature, pressure, or strain in manufacturing and metallurgy
• Medical technology: Surgical lasers, diagnostics, and minimally invasive monitoring
• Infrastructure and security: Distributed acoustic sensing for pipelines, railways, or perimeter monitoring
• Research and aerospace: High-precision measurements in extreme environments, including high temperature, vacuum, or radiation
