Aberrations of spectrographs with the correction of the schmidt camera effected in the collimator

Of the different ways to introduce the Schmidt correction of the camera in a spectrograph, the case was studied in which it is effected in the collimator. Equations which describe the form of the wave-front at one side of the grating as function of the form at the other side were found. The sixthord...

Equations which describe the form of the wave-front at one side of the grating as function of the form at the other side were found. The sixthorder terms in the correction to compensate for the deformation of the wavefront in the path from the collimator to the grating and to the mirror were also found. The aberrations for a correction which is symmetrical around the collimator axis were calculated. The limit of camera aperture for which these aberrations are tolerable is between F/D =4 and F/D=3 according to the size and number of lines of the grating. © 1971 Taylor & Francis Group, LLC. 1971 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_00303909_v18_n11_p829_Simon http://hdl.handle.net/20.500.12110/paper_00303909_v18_n11_p829_Simon
