Abstract: Embodiments disclosed include methods and apparatus for Fluorescent Enhanced Photothermal Infrared (FE-PTIR) spectroscopy and chemical imaging, which enables high sensitivity and high spatial resolution measurements of IR absorption with simultaneous confocal fluorescence imaging. In various embodiments, the FE-PTIR technique utilizes combined/simultaneous OPTIR and fluorescence imaging that provides significant improvements and benefits compared to previous work by simultaneous detection of both IR absorption and confocal fluorescence using the same optical detector at the same time.

Abstract: Improvements in spectroscopy are disclosed herein that rely on the interaction of both an infrared beam and a probe beam with a sample. These beams are used in a pump-probe arrangement, with a fiber optic probe collecting the beams of infrared and probe radiation from the infrared source and delivering it to the sample. At least a portion of the beam of infrared radiation and the beam of probe radiation overlap one another on the sample. The fiber also collects probe radiation that has interacted with the sample. A detector can use this collected signal to indicate an intensity of the collected probe radiation, and an analyzer can generate a signal indicative of infrared absorption of the sample adjacent the fiber.
