| Abstract | The novel diamond [micro]ATR sensor accessory for ATR FT-IR spectral acquisition using an infrared microscope with a gem quality round brilliant cut diamond as an IRE was fabricated. The ATR spectrum under total internal reflection phenomenon within the diamond can be collected. Since diamond is the hardest material, it can be used for characterization of rough surface, hard, and rigid samples. Due to the small sampling area of diamond tip, the small sample can be employed by the diamond [micro]ATR sensor. In this work, characterizations of single fibers by a novel diamond [micro]ATR sensor were studied. The surface information of the single fibers were achieved. The observed spectra show the different spectral features between untreated fibers and chemical-treated fibers. The spectra acquired by the novel diamond [micro]ATR sensor were similar to those acquired by the conventional ATR technique. The spectral intensity of spectra acquired by the diamond [micro]ATR sensor is better than those obtained by the conventional ATR due to the better contact. |
