The embodiment provides a spectrometer and assembling method thereof. The spectrometer includes a base, a light input element, a light splitting element, an image sensor and a shading element. The light input element is disposed on the base for receiving an optical signal. The light splitting element is disposed on the base for incident the optical signal received by the light input element to split the optical signal into a plurality of spectral components. The image sensor is disposed on the base and has a sensing surface for receiving the spectral components. The sensing surface has a virtual center line extending in the arrangement direction of the spectral components. The shading element is disposed between the light splitting element and the image sensor according to an optical influence factor and is located on a projection path of portion of the spectral components, and shades the portion of the spectral components to suppress the excessively high light intensity of the spectral components.
