Abstract[English]
An optical system (100) and a corresponding method for efficiently wavelength dispersing an incoming beam (201) with a grism (101), and spatially separating the dispersed beam from the incoming beam (201) by total internal reflection in the grism (101). The grism (101) comprises a first prism surface (102), a second prism surface (103) with a grating (105), and a third prism surface (104), and is arranged in the optical system (100) to receive the incoming beam (201) with the first prism surface (102). The second prism surface (103) is configured to receive the incoming beam (201) from the first prism surface (102), and to diffract the incoming beam (201) to form a diffracted beam (202). The first prism surface (102) is configured to receive the diffracted beam (202) from the second prism surface (103) and to reflect the diffracted beam (202) by total internal reflection towards and/or out of the third prism surface (104).[French]
L'invention concerne un système optique (100) et un procédé correspondant pour disperser efficacement une longueur d'onde d'un faisceau entrant (201) avec un grism (101), et séparer spatialement le faisceau dispersé du faisceau entrant (201) par réflexion interne totale dans le grism (101). Le grism (101) comprend une première surface de prisme (102), une deuxième surface de prisme (103) avec un réseau (105), et une troisième surface de prisme (104), et est agencé dans le système optique (100) pour recevoir le faisceau entrant (201) avec la première surface de prisme (102). La seconde surface de prisme (103) est configurée pour recevoir le faisceau entrant (201) à partir de la première surface de prisme (102), et pour diffracter le faisceau entrant (201) pour former un faisceau diffracté (202). La première surface de prisme (102) est configurée pour recevoir le faisceau diffracté (202) à partir de la deuxième surface de prisme (103) et pour réfléchir le faisceau diffracté (202) par réflexion interne totale vers et/ou hors de la troisième surface de prisme (104).
