Abstract: A spectrometer (100) and an optical input portion (32) thereof are disclosed. The optical input portion (32) comprises an assembly structure (322), and the assembly structure (322) is formed at a hole wall (321) of a through hole (3211) of the optical input portion (32). A light (L1) is incident into a dispersing element (2) of the spectrometer (100) along an optical path (13) after passing through the through hole (3211), and is dispersed by the dispersing element (2). The assembly structure (322) is used to be detachably assembled with an optical element (200). When the optical element (200) is assembled with the assembly structure (322), an optical axis of the optical element (200) is linked to the optical path (13). As a result, the light (L1) passing through the optical element (200) is incident to the dispersing element (2) along the optical axis and the optical path (13).

Abstract: A spectrometer includes an input unit for receiving an optical signal, a diffraction grating disposed on the transmission path of the optical signal for dispersing the optical signal into a plurality of spectral rays, an image sensor disposed on the transmission path of at least a portion of the spectral rays, and a waveguide device. A waveguide space is formed between the first and second reflective surfaces of the waveguide device. The optical signal is transmitted from the input unit to the diffraction grating via the waveguide space. The portion of the spectral rays is transmitted to the image sensor via the waveguide space. At least one opening is formed on the waveguide device, and is substantially parallel to the first and/or second reflective surface. A portion of the spectral rays and/or the optical signal diffuses from the opening out of the waveguide space without reaching the image sensor.
