An angled reflection probe works well for reflection and backscattering measurements of powders and dense solutions. It has the same 6-around-1 fiber bundle configuration as our standard reflection probes, but with a 30º angled window at a small distance from the fiber bundle tip. This serves to reduce specular reflection effects when the probe is immersed in powders or dense solutions, and allows the probe to maintain direct contact with those samples for easy and consistent measurements.

  • 6-around-1 fiber bundle design at probe end
  • Stand-off window at 30º allows direct contact with powders and solutions
  • Available in premium- and lab-grade, 200 μm and 400 μm core fibers for UV-VIS or VIS-NIR use
