Abstract: front page image
(EN)A spectrometer comprising an incident-side light waveguide for emitting a light flux containing a plurality of wavelength components and approximated by a Gaussian beam, a light incident unit installed on the emitting side of the incident-side light waveguide and having a collimate lens that converts a Gaussian beam-approximated light flux emitted from the incident-side light waveguide into almost parallel light flux, and a light emitting unit having a diffraction lattice that receives a light flux converted into an almost parallel light flux by the collimate lens, spectrally separates a light flux by emitting light fluxes different in emitting direction depending on a wavelength, and has grooves in the surface thereof, and a plurality of condensing lenses that condense respective light fluxes separated by the diffraction lattice.
(FR)L'invention porte sur un spectromètre comportant: côté incidence, un guide d'ondes lumineuses émettant un faisceau lumineux approximativement gaussien dans plusieurs longueurs d'onde; côté émission dudit guide d'ondes, une unité d'incidence de lumière présentant une lentille collimatrice convertissant ledit faisceau en un flux lumineux quasi parallèle; et une unité émettrice de lumière comportant: un réseau diffracteur recevant le flux quasi parallèle et le séparant en flux séparés dont la direction diffère en fonction de la longueur d'onde; des rainures à sa surface; et un ensemble de lentilles condensatrices condensant les différents flux lumineux séparés par le réseau diffracteur.
