Fiber Optic Liquids Probe
The Fiber Optic Liquids Probe is useful for remote liquids analysis in the 1.5 - 18µm wavelength range. The hexagonal fiber bundle design incorporates a single, large diameter sending fiber in the probe's center interfaced with the instrument's source, while 7 smaller diameter returning fibers surround the center fiber and extend back to the instrument's detector. The fiber material available for spectral analysis to cover the wavelength range include either Chalcogenide for performance from 1.5 - 6µm or Silver Halide from 4 - 18µm.
This double pass transmission technique uses a collimating lens to enable efficient coupling with the spectrophotometer's beam along with the efficient collection of IR radiation reflected back by the fiber probe's mirror. Due to much lower mid-IR attenuation in liquids, the collimated beam design of a double pass (or multiple pass) liquids cell is necessary to achieve greater signal sensitivity. This design is easily realized when the collimating lens objective and reflecting mirror are assembled to a customized pathlength that is dependent upon the application. Available pathlengths range from 0.020 - 0.50mm. Assemblies can be fabricated from either Titanium, Hastelloy, PEEK or Stainless Steel. Fiber bundle lengths are typically up to 2 meters although longer lengths are available upon request.
The Fiber Optic Liquids Probe is compatible with all FTIR spectrophotometers with SMA terminated optical couplers or spectrophotometer interface.
