Abstract
The optical measuring device includes a light source that outputs light of a plurality of wavelengths; a sensor head including a conversion lens that converts light incident via a light guide part, which includes a plurality of cores, into parallel light, and an objective lens that irradiates the light in which chromatic aberration is generated to a measurement object; and a spectroscope that acquires reflected light reflected by the measurement object and condensed by the sensor head via the light guide part and measures a spectrum of the reflected light. In the sensor head, a shield that shields light is arranged between the conversion lens and the objective lens to inhibit light emitted from one core among the plurality of cores included in the light guide part from entering cores other than the one core as the reflected light.
