Reflection/Backscattering Probes
 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.
Features
-
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.
Non-metallic Ferrule Option
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.

* LTBR stands
for Long Term Bend Radius, the bend radius allowed long term (such as for
storage) before damaging the fiber.
** STBR stands for Short Term Bend Radius, the momentary bend radius
allowed before damaging the fiber.
