Abstract: A spectrometer comprising a waveguide module, a diffractive component, and a light sensor is provided. The waveguide module has a first reflective surface, a second reflective surface opposite to the first reflective surface, and a light channel between the first reflective surface and the second reflective surface. The diffractive component has a diffractive surface and a plurality of strip-shaped diffractive structures located on the diffractive surface. The sharpness of the profile of the strip-shaped diffractive structures on a first side of the diffractive surface is greater than that on a second side of the diffractive surface. When viewed along a direction perpendicular to the second reflective surface, the first side of the diffractive surface is positioned between the first reflective surface and the second reflective surface with a distance away from the second reflective surface. A method for assembling the spectrometer and an assembling system are also provided.

Abstract: The present application discloses an optical sensing module, an optical mechanism of a spectrometer, and a spectrometer. An optical sensing module according to one embodiment comprises an optical sensing component and an optical fiber. The optical sensing component includes at least a row of optical sensing units. The optical fiber is made of a transparent material and has a cylindrical curved surface. A side of the cylindrical curved surface faces the optical sensing units to converge at least a portion of an incident light received by the optical sensing units. With techniques of the present application, the amount of light collected at the optical sensing component can be increased for it to be suitable for applications such as miniaturized apparatuses and systems, thus improving the overall efficiency of optical reception and utilization therein.

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.

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).
