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). ### Product Visuals: ![OFSCN® Fiber Bragg Grating 3D Force Sensor 01](https://forum.ofscn.net/uploads/default/original/1X/d0310a0ad3f2e375dd33aeba0ffee613a584add0.jpeg) ![OFSCN® Fiber Bragg Grating 3D Force Sensor 02](https://forum.ofscn.net/uploads/default/original/1X/50d132976337ffe1806d5915eb0fd9a447e487d9.jpeg) ### 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](https://www.ofscn.net/fbg-products/temperature-sensor-300.html) for temperature compensation. - **Connectors:** Default FC/APC; ST, LC, and SC (PC/APC) are available upon request.
