Abstract: Disclosed is a spectrometer including a slit unit and a collimating member sequentially arranged along a path of pre-diffraction radiation light, a focusing member and a detection unit sequentially arranged along a path of post-diffraction radiation light, and the diffraction grating located between the collimating member and the focusing member, wherein the slit unit, the collimating member, the diffraction grating, and the focusing member are seated in one plane and are spaced apart from each other by a predetermined distance, and the detection unit is spaced apart from one plane and is located under or above the diffraction grating.
