Fiber Optic Probes for Material Science

Optromix fiber optic probes for process spectroscopy are based on coherent bundle design and provide the best coupling efficiency with spectrometers, light emitters (LED, lasers, lamps, etc.), and media of spectral analysis to investigate its reflectance, fluorescence or absorption spectra. Process spectrometers based on Optromix fiber probes are relied upon by professionals around the world to deliver accurate spectral measurements for material scientists. Material science is accountable, to give just a few examples, for discoveries of rubbers, plastics, and biomaterials. In addition to this, spectroscopy could be employed in the chemical deposition process for graphene foam fabrication for endpoint detection and process control, and morphology or crystallinity can be distinguished using Raman spectroscopy methods.
Spectroscopy has several uses in material science. Raman spectroscopy can provide an understanding of crystalline alignment, laser-induced breakdown spectroscopy is utilized to identify atomic composition, and emission monitoring spectroscopy analyzes plasma composition during chemical deposition processes.
Optromix fiber optic probes are the ideal solution for analyzing large or awkwardly shaped samples, monitoring real-time kinetic reactions, sampling in vivo, and other application where it is difficult to bring the sample to the spectrometer. Fiber optic probes are one of the most widespread tools in modern spectroscopy with their flexibility and user-friendliness. There are four of the most common fiber optic probes: reflective probes, dark-field reflection probes, transflectance dip probes, and Raman probes.
The reflection probe is the most basic fiber optic probe, which in its simplest form consists of a bifurcated fiber where the distal (bundled) end is placed in a metal sheath instead of a SMA connection;
The dark-field probe works by illuminating the sample with an annulus of seven fibers. The diffusely reflected light is then collected by a bundle of seven fibers in the center of the probe which directs the light to the spectrometer in a sit configuration;
The key functional difference of the transflectance dip probes is the presence of a cavity which fills with the liquid sample. This cavity contains an optically transparent window placed at the distal end of the fiber and a small mirror placed at the bottom of the cavity to reflect the transmitted light back referred to as a transflectance. It is important to note that transflectance measurements can also be made using a dark-field reflectance probe configuration;
Raman probes are capable of directing and focusing the monochromatic excitation source (typically a laser) to the sample, collecting the scattered light and then directing it to the spectrometer.
Spectroscopy gives scientists in this area the tools they require to develop the cutting-edge materials of the future.
