Abstract

An inclined-slit spectrograph includes a light source, an inlet slit, a grating and a detector including window through which the light beam diffracted by the grating is transmitted with part of the diffracted light beam generating reflections on the window or between the window and the sensitive surface of the detector. A rectangular inclined inlet slit compensates for spectral resolution losses.
