    Abstract: A spectrometer 1A is made up of : an optical body 10 within which a light separation path is set along which an object light to be separated propagates; a light entry slit 16 through which the object light enters; a diffraction grating 17 for spectrally separating the incident object light; and a photodiode array 18 for detecting the object light separated by the diffraction grating 17. As an optical member for optically interconnecting the optical body 10 and the photodiode array 18, an optical connection member 20 is provided, with its light entry surface 21 for the separated object light in contact with the upper surface 11 of the optical body 10, with its light exit surface 22 in contact with the photodiode array 18, with the light exit surface 22 tilted by a specified angle relative to the light entry surface 21. Thus, the spectromoter capable of bringing about sufficient accuracy of placing optical elements in a simple constitution while bringing down cost is realized.

    Abstract: Methods and systems for carrying out the distribution of light in a ray pathway (21) into wavelength components (21 - 27) comprising optical elements (10, 11) of the diffraction grating type that diffract the said light into several spectral orders (m). The invention is characterised in that at least two diffraction grating surfaces are placed sequentially in the ray pathway whose orientations and grating constants are selected such that the wavelength components that are diffracted at the grating surfaces into the respective orders, whose sum (M = m1 + m2) is constant, emerge from the last grating surface (11) in essentially the same direction.

    Abstract: L'invention vise à intégrer, au moment de la phase de fabrication, une fonction d'interféromètre statique à deux ondes sur un photodétecteur afin de constituer un spectromètre statique miniature par transformée de Fourier. L'interféromètre est essentiellement constitué par une lame (LC) dont une première face plane (F1) coïncide avec un plan d'image (IM) sur des éléments photosensibles semi-conducteurs (EPS) et dont la deuxième face (F2) n'est pas parallèle à la première face (F1). Cette deuxième face (F2) réfléchit une onde déphasée en fonction de l'épaisseur locale de la lame (LC) par rapport à l'onde incidente (E0) qui interfère avec elle.
