Abstract
A fiber optic probe for ATIR (Attenuated Total Internal Reflection) spectrophotometry. The probe includes a housing that contains an optical element or lens, a light-transmitting fiber that directs incident light to the lens, a light-receiving fiber that receives reflected light from the sample interface, a coupler for holding these components in precise alignment, and a flexible armor casing that provides strain relief and protection for the optical fibers. The lens is shaped and dimensioned so that light from the transmitting fiber is reflected at the interface between the lens and the surrounding medium (such as a liquid to be analyzed). The reflected light is transmitted via the transmitting fiber to a suitable spectrophotometer, where the light signal is recorded and analyzed to determine the composition of the sample. The probe is particularly suitable for analyses of fluids and slurries with high optical absorbance.
