Abstract
Methods and devices for evaluating solid-state surface properties use infrared absorption of lattice vibration. These methods and devices are characterized by reflection spectrometry by injecting infrared rays from the reverse of the solids, placing a light transmissible solid-state sample in ways that its surface faces the plane reflex mirror on the interaction region formed by reflected infrared rays, or by injecting infrared rays from the rear of a sample or from the front thereof after upright installation of the light transmissible solid-state sample through a slit created across the plane reflex mirror or on the surface of plane reflex mirror. These methods and devices enable simplified and accurate reflection spectrometry of solid-surface properties, featuring an economical system configuration that dispenses with expensive prism, unlike the conventional ATR method.
