Abstract: A spectrometer and a micro-total analysis system are provided. The spectrometer includes a waveguide structure, a light source, a collimating mirror, a reflection grating, and a light extraction structure. The collimating mirror is configured to convert light, which is emitted from the light source, passes through the waveguide structure, and is incident on the collimating mirror, into collimating light. The reflection grating is configured to allow emergency angles of light of different wavelength ranges among the collimating light incident on the reflection grating to be different, so that the light of different wavelength ranges has an offset in the total reflection propagation process. The light extraction structure is located on the reflection surface of the waveguide structure through which the light of different wavelength ranges passes in the total reflection propagation process, so that the light of different wavelength ranges emits from the light extraction structure.
