Endoscopic Fiber Optic Reflection Probes

Endoscopic Reflection Fiber Optic Probe from FlexiSpec® product line is designed to measure Diffuse and Specular Reflectance, Backscatter, or Fluorescence for biomedical applications.

art photonics GmbH offers Endoscopic Reflection Probe with thinnest probe tip diameter (0.5mm) and unique “7+1” fiber bundle configuration.  Based on Bifurcated Fiber Optic Bundle construction with” IlluminatingLeg to carry light from a source to a sample – and “Reading” Leg to carry reflected light to a Spectrometer.

Unlike traditional fiber arrangement in reflection probes, which have “6-around-1” – fiber bundle configuration, our probes have “7 around 1”. That’s because in such configuration Signal/ Noise ratio is much higher than in traditional ones.

All Illuminating Fibers of our Endoscopic Reflection Probes are metal coated that’s why cross-talk between the illuminating fibers is blocked, and in result – Signal/Noise ratio is higher than in similar probes with fiber polymer coatings.

Our Endoscopic Reflection Fiber Probes are available with Round-to-Round (R/R) or Round-to-Line (R/L) design.
