Abstract / Hauptanspruch
A confocal measurement device (1) includes a light source (10) that outputs white light, an optical coupler (20), a sensor head (100) that applies light with a chromatic aberration caused therein to a measurement object (200), and a spectroscope (30) that acquires reflected light which is reflected by the measurement object (200) and measures a spectrum of the reflected light. The optical coupler (20) is a filter type coupler (22) or a spatial optical system type coupler (23) that brings a first transmission waveform when light is transmitted from a first optical fiber cable (11) to a second optical fiber cable (12) and a second transmission waveform when light is transmitted from the second optical fiber cable (12) to a third optical fiber cable (13) close to each other.
