ATR Immersion Probes

ATR technology (Attenuated Total Reflectance) allows us to take advantage of the total reflection of the light transmitted from an optically dense medium to a less dense medium. The light at the boundary layer (sapphire/liquid) penetrates approximately a quarter of the wavelength into the less optically dense medium, where it can be absorbed. With our ATTENUTO probe, the optical path length falls within the sub-micrometer range, allowing for the analysis of highly concentrated solutions while eliminating time-consuming dilution steps.


Complete Range of Accessories
As well as our fiberoptic probes, we offer everything you need for connecting the probe to your spectrometer. Our wide range of accessories includes high-quality extension fibers for the UV, VIS , and NIR ranges.

We also offer process kits to protect the optical fibers at the point of installation. These can consist of steel mesh tubing, including a solid casing in which the extension fibers are coupled.
