Title (EN) SPECTROMETER USING DIFFRACTION LATTICE
(FR) SPECTROMETRE A RESEAU DIFFRACTEUR
(JA) 回折格子を用いた分光装置
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.
(JA)複数の波長成分を含んでいてガウシアンビームで近似される光束を出射する入射側光導波路と、入射側光導波路の出射側に設置され、入射側光導波路から出射されたガウシアンビームで近似される光束を、略平行光束に変換するコリメートレンズとを有する光入射部と、コリメートレンズにより略平行光束に変換された光束が入射され、波長ごとに出射方向の異なる光束を出射することで光束を分光する、表面に溝を有する回折格子と、回折格子によって分光された各光束をそれぞれ集光する、複数の集光レンズを有する光出射部とを備えている。
