Probes and Accessories

At pioNIRS, we can provide all you need for quick and easy TD-NIRS measurements!

Our probes are fiber-based and are equipped with their specific IRFbox to enable fast and easy Instrument Response Function acquisition for more accurate measurements.

All accessories are designed by our engineers to make your measurement as simple and fast as possible.

S (standard) and B (body) optode families, provide a 90° bend to the laser beam ensuring compact optical probes, while keeping high transmission efficiency.

S1-FC probe:

The S1-FC optode is an easy-to-use fiber replaceable solution, optimal for measurement on semi-planar surfaces like muscles and other biological media. Compact, lightweight and durable. (Also available with SMA fiber connectors).

1 Source – Detection (SD) separation (distance) is the mean distance between the injection point and the detection location.
2 Flexibility: internal flexibility scale: Rigid – Medium – High
3 Fiber layout can be either removable (fiber can be removed and replaced) or fixed (unremovable fibers). The probe injection geometry can be parallel or perpendicular to the measuring surface.
