OFSCN can currently achieve a minimum customizable outer diameter of **0.5 mm** for its [OFSCN® 500°C Fiber Bragg Grating Temperature Sensor](https://www.ofscn.net/fbg-products/temperature-sensor-350.html). The [OFSCN® OFDR Micro All-Metal Strain Sensor](https://www.ofscn.net/fbg-products/strain-sensor.html) also offers a compact design with an outer diameter of 0.6 mm.

Regarding minimally invasive medical scenarios, the provided information does not detail specific applications in this field.
