A probe is a compact, versatile way 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.

We offer nearly 40 standard reflection/backscatter probes in a variety of fiber core sizes and wavelength ranges, and can also customize a probe to your exact specifications.

Reflection Probe Type Applications Grades Fiber Types Core Diameters
General Purpose General purpose diffuse or specular reflectance from solids; fluorescence; color Lab-grade, Premium SR, UV-VIS, VIS-NIR 200 – 600 μm
With Reference Leg Reflectance with reference monitoring of the light source using an extra leg Lab-grade, Premium UV-VIS, VIS-NIR 200 μm
Broadband Reflectance with expanded wavelength coverage; 2 read legs (UV/VIS and VIS/NIR) Lab-grade, Premium MIXED 200 μm
Angled Reflectance and scattering from powders; highly scattering solutions Lab-grade, Premium UV-VIS, VIS-NIR 200 – 400 μm

Reflection applications in solids:

  • Plastics, metals, paints and coatings; thin films and optical filters
  • Inks, dyes and graphics arts
  • Industrial textiles and clothing
  • Biomedical samples such as human skin and other cellular tissue
  • Plants, marine life

Reflection applications in liquids and powders:

  • Milk and other beverages
  • Paints, inks and dyes
  • Resins and bulk powders
  • Suspended particulate matter in slurries and turbid liquids
  • Fluorescence of liquid samples
