Abstract
A spectrometer includes a light source to project a light beam to a target object, a spectral element to disperse the light beam reflected by the target object and including a diffraction element to diffract the light beam, and a light receiving element to receive, at pixels, light beams with different spectral characteristics from each other dispersed by the spectral element, wherein the diffraction element and the light receiving element are integrally formed.
