Remspec Corporation is the premier source for high-quality, high-performance fiber-optic spectroscopy systems that operate in the mid-infrared. We invented the highest performance ATR system on the market and our patented reflectance and transmission probes are second to none. Remspec’s fiber-optic technology is ideal for non-invasive analysis of soft tissue.

Contact ATR spectra are obtained by pressing an ATR crystal firmly against the target tissue, giving the mid-IR spectrum of the surface layer to a depth of a few microns. Changes due to tissue degradation, or following treatment with lotions etc., can be characterized rapidly.

Typical mid-IR spectra of soft tissue include characteristic amide I and amide II bands between 1700 and 1600 cm^-1; these features originate from proteins
