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.
