A reflection/backscatter probe is a compact, versatile sampling option to measure diffuse and specular reflectance, backscatter, or fluorescence from samples as varied as solids, solutions, and powders. Reflection and backscatter measurements can provide quantitative information about the color, appearance, and chemical composition of a sample.



  • General purpose -- ideal for diffuse or specular reflectance from solids; fluorescence; color
  • XSR fibers -- probe assembly comprises extreme solarization-resistant fibers (180-800 nm)
  • Probe design -- 6-around-1 fiber bundle design, with 6-fiber leg connecting to light source and single-fiber leg connecting to spectrometer
