Abstract
A confocal measurement device includes a light source that outputs white light, an optical coupler, a sensor head that applies light with a chromatic aberration caused therein to a measurement object, and a spectroscope that acquires reflected light which is reflected by the measurement object and measures a spectrum of the reflected light. The optical coupler is a filter type coupler or a spatial optical system type coupler that brings a first transmission waveform when light is transmitted from a first optical fiber cable to a second optical fiber cable and a second transmission waveform when light is transmitted from the second optical fiber cable to a third optical fiber cable close to each other.
