IPC: G01N21/31

Abstract: A spectral confocal measurement device includes a light source portion, configured to emit a broad-spectrum light beam with a certain wavelength range in a first predetermined path; an optical sampling portion, configured to converge the broad-spectrum light beam emitted from the light source portion on different measurement surfaces of an object to be measured, and output a reflected light in a second predetermined path that is different from a reverse direction of the first predetermined path; and a measurement portion, configured to receive and process the reflected light from the optical sampling portion to obtain a measurement result. The device can improve measurement accuracy and reduce production costs. In addition, a spectral confocal measurement method is also provided.
