Reflection probes are designed to capture spectral information from both diffuse and specular materials. In this setup, light from a source is directed through six illumination fibers toward the sample, while the reflection is collected by a seventh fiber positioned at the center of the probe tip. This seventh fiber is then connected to a spectrometer, which is configured to measure the appropriate wavelength range of interest.
Applications:
- Surface Analysis: Used to analyze surface properties of materials, such as coatings, paints, and films, by measuring the reflected light.
- Food and Agricultural Industries: Applied in the assessment of quality or ripeness of food products based on reflected light, useful in non-destructive testing.
- Pharmaceuticals: Used for assessing the surface of pharmaceutical tablets, coatings, and other solid materials.
- Chemical Industry: Helps in surface characterization of chemical products, monitoring surface coatings, and layer thickness.
