Abstract
A spectroscopic measuring apparatus and method are provided. The apparatus includes a first light source, object, microlens, and imaging lenses, an optical fiber, a spectrometer and a position controller. The object lens to allows light from the first light source to be incident on a stage configured to support a measurement object. The microlens is disposed between the object lens and the stage. The imaging lens images light reflected from the measurement object. The optical fiber has an input terminal disposed on a first image plane of the imaging lens. The spectrometer is disposed at an output terminal of the optical fiber. The position controller controls positions of the object lens, the microlens, and the optical fiber, and adjusts the position of the object lens so that a focus of the object lens is positioned at a virtual image position of a virtual image generated by the microlens.
