QR Premium Ocean Optics Reflection Backscatter Probe

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

The probes consist of 6 illumination fibers around 1 read fiber.

The 200um and 400um fibers are all encased in a 1/4" OD ferrule.

The 600 micron fibers are in 1 1/8" OD ferrule
