Our premium-grade reflection and backscattering probes are durable, high-quality patch cords that consistently deliver uniform results with minimal signal variance. Available in a variety of fiber core sizes and wavelength ranges, they are a convenient way to measure specular or diffuse reflectance from a surface. Our 600 μm core probes can even be used to excite and sense fluorescence from solid samples.
Also consider our:
- Great for field and industrial use, or other rough handling environments
- Superior quality and handling for aesthetically demanding applications like medical labs
- 6-around-1 fiber bundle design
- 6-fiber leg connects to light source, single-fiber leg connects to spectrometer for best performance
