Welcome to the OFSCN® Technical Inquiry forum.
The OFSCN® Fiber Bragg Grating 3D Force Sensor described above is a high-precision instrument designed for multi-directional pressure measurement on solid surfaces or medical puncture force analysis.
Key Technical Characteristics:
- Multi-Axis Measurement: The sensing unit consists of a hard alloy base with three Fiber Bragg Gratings (FBGs) arranged longitudinally at 120-degree intervals. This allows for the decoupling of forces in multiple directions.
- Versatile Form Factors: It is available in a standard industrial version and a handheld “pen-style” version (default 4.0 mm diameter) for ergonomic use.
- Customizable Tips: The sensing end can be configured as a flat head for surface pressure or sharpened for medical puncture applications.
- Dimensions: Common outer diameters include 1.5 mm, 2 mm, 4 mm, and 6 mm, with further customization available.
- Calibration: Each unit is factory-calibrated for vertical force vs. wavelength shift, provided with a linear calibration formula (N/pm).

Technical Specifications & Links:
- Temperature Range: Standard operation from -20°C to +55°C. For applications requiring high precision under varying temperatures, we recommend integrating an external OFSCN® Fiber Bragg Grating Temperature Sensor for temperature compensation.
- Connectors: Default FC/APC; ST, LC, and SC (PC/APC) are available upon request.
