Description
These probes are especially useful for embedding into process streams for in situ, real-time sample monitoring.
The are more suitable for liquid solutions.
The probe has two fibers projecting light through a shared lens. Light from the source is focused by the lens onto a mirror across the sample gap. The light is reflected back through the lens to the read fiber, which brings the light to the spectrometer. The lenses are focused for use in water, and if used in air, will be severely out of focus and inefficient.
