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 diffraction grating comprise a substrate and a plurality of connected diffraction structures formed on the substrate. Each diffraction structure is in the shape of a column and arranged along a concave cylindrical surface, and an axis of each diffraction structure extends along a generatrix of the concave cylindrical surface. A section contour is obtained by a cross section of the diffraction structures. The cross section is perpendicular to each axis of the diffraction structure. The section contour shows the connecting line of apexes of the diffraction structures as a reference curve having a plurality of first inflection points, wherein the diffraction structures are configured for separating the optical signal into a plurality of spectral components and focusing the spectral components onto a focal surface.
