The light is directed from the echelle immersions grating to the cryogenically cooled detector on the second side of the spectrometer housing.Īstronomical near-infrared echelle gratings The light is directed from the cross-disperser grating to the echelle immersions grating. Light from the entrance slit is directed to the cross-disperser grating. A cryogenically cooled detector is located in the housing on the second side of the spectrometer housing. An echelle immersions grating and a catadioptric lens are positioned in the housing to receive the light. An entrance slit is on the first side of the spectrometer housing and directs light to a cross-disperser grating. Echelle grating multi-order imaging spectrometer utilizing a catadioptric lensĪ cryogenically cooled imaging spectrometer that includes a spectrometer housing having a first side and a second side opposite the first side.
