This attenuated total reflection probe is specifically designed for measuring highly absorbent samples, even up to the 4000-5000 AU/cm range. The probe can be inserted directly into the sample for spectral measurements without sample dilution. Typical applications involve analysis of pure inks, dyes and crude oil samples. What’s more, this probe can be used as a general deposition probe if the refractive index of the material that is depositing on the probe tip is greater than that of the probe’s sapphire crystal, or is greater than 1.7.

  • Ideal for samples with high optical density
  • Connects to light source and spectrometer with two 600 μm fibers
  • Suitable for 4000 – 5000 AU/cm samples, no sample dilution needed
