Our Fiber Optic Reflection / Backscattering Probes are used for measuring specular or diffuse reflectance from a surface, fluorescence from solid surfaces, or backscattering and fluorescence in solutions and powders. These Reflection / Backscattering Probes couple to our spectrometers and light sources to create small-footprint optical-sensing systems for measuring reflection and fluorescence from solid surfaces, or backscattering and fluorescence in liquids and powders. Reflection probes can be optimized for the UV/VIS (250-800 nm) or VIS/NIR (400-2100 nm), or a combination of both ranges.
Application Versatility. Measure reflection and fluorescence from solid surfaces, or backscattering and fluorescence in liquids and powders
UV-VIS or VIS-NIR Wavelength Ranges. Optimize the probe for the UV/VIS (250-800 nm) or VIS/NIR (400-2100 nm), or a combination of the UV-VIS and VIS/NIR
Multiple Probe Options. Options include your choice of ferrule material (stainless steel or plastic) and probe window design (standard or angled to 30°)
The R400-7, R200-7 and R600-7 each consists of a tight bundle of 7 optical fibers in a stainless steel ferrule -- 6 illumination fibers around 1 read fiber. The fibers in the R200-7 are 200 µm in diameter, the fibers in the R400-7 are 400 µm in diameter, and the fibers in the R600-7 are 600 µm in diameter.
The RP200-7 consists of a bundle of 200-µm fibers in the same 6-around-1 design. The probe has a plastic ferrule that is useful for applications where non-metallic probes are required, such as those involving corrosive samples.
