Fiber Optic Sensors

Resonetics® is a leading manufacturer of fiber optic sensors and readout units for the medical device industry. Our sensors are commonly used in minimally invasive procedures to measure pressure, temperature, and force at the tip of a catheter. Their extremely small size and resistance to radio frequencies, electromagnetic interference, and microwave radiation ensure reliable performance in demanding clinical environments. We offer a standard line of fiber optic sensors to enhance your device, or our engineering team can develop custom solutions tailored to your specific application.

Benefits of Fiber Optic Sensors

  • Sensor diameter as small as 0.8 French
  • Lead-in fiber diameter less than 0.5 French
  • Exceptionally flexible glass fiber offers superior deliverability without kinking
  • Front-looking configuration of sensor tips prevents side-facing/wall-bouncing measurement artifacts
  • Absence of metallic components provides immunity to RF, MW, and MRI interference

Fiber Optic Sensor Technology

Our fiber optic sensors function by detecting changes in light as it passes through the sensing element. A readout unit transmits light through an optical fiber to the sensor tip, where a mirror reflects the coded signal back for analysis. Features within the sensor alter the light in response to external parameters such as pressure, temperature, and force. Because Resonetics’ sensing technologies operate independently of light loss, they remain robust and reliable throughout therapy.

Fiber Optic Sensor Models

All of our fiber optic sensor models are used in various FDA and CE-approved medical devices and diagnostic equipment.

  • FOP-M200: Features a 200-micron diameter and a standard range of ±300 mmHg relative to atmospheric pressure
  • FOP-M260: Features a 260-micron diameter and a standard range of ± 300 mmHg relative to atmospheric pressure
  • FOP-MIV: Assembled on a fully robotized manufacturing line and features a 550-micron diameter, a ± 300 mmHg range, and a 0-150 psi range

Fiber Optic Sensor Manufacturing Capabilities
