Abstract
A chromatic confocal sensor includes a light source portion that emits a plurality of light beams having different wavelengths; an objective lens that converges the plurality of light beams at different focal positions; an emission port from which measurement light reflected by an object to be measured at the focal positions out of the plurality of light beams is emitted; a position calculation portion that calculates a position of the object to be measured based on the emitted measurement light; an observation portion including an observation light source that emits observation light and an image sensor; and a beam splitter that emits at least a part of the measurement light that passes through the objective lens to the emission port and emits at least a part of the observation light that passes through the objective lens and is reflected by the object to be measured to the image sensor.
