Abstract: A miniature spectrometer comprises an input unit, an image capture unit, a miniature diffraction optical grating, an optical grating accommodation slot, a cushion, and an affixing plate. The miniature spectrometer may further comprise a waveguide device, and the optical grating accommodation slot is positioned in a space defined by an opening of the waveguide device. The input unit receives an optical signal which proceeds in the waveguide device. The miniature diffraction optical grating separates the optical signal into numerous spectral components to be projected onto the image capture unit. The cushion is stacked on the miniature diffraction optical grating, with both disposed in the optical grating accommodation slot. The affixing plate is disposed on the waveguide device to apply a compressing force on the cushion to affix the miniature diffraction optical grating in the optical grating accommodation slot.

Abstract: An optical system comprising an input member, a predetermined output plane and a reflection type diffraction grating is disclosed. The input member receives an optical signal. The reflection type diffraction grating comprises a grating profile curved surface and a plurality of diffraction structures. The diffraction structures, which separate the optical signal into a plurality of spectral components, are respectively disposed on the grating profile curved surface by a plurality of pitches. At least some pitches are different from each other, so that the spectral components are emitted to the predetermined output plane in a direction substantially perpendicular to the predetermined output plane. The grating profile curved surface is used for focusing the spectral components on the predetermined output plane.
