Abstract
Correction optics () are disposed in an optical path directly behind an entry slit () of a spectrometer () and configured to warp a straight object line shape (A) of the entry slit () into a curved object line shape (B) from a point of view of the projection optics (). The warping of the correction optics () is configured such that a curvature (R) of the curved object line shape (B) counteracts an otherwise distorting curvature (R) in a projection (A) of the straight object line shape (A) by the projection optics () without the correction optics (). As a result, the spectrally resolved image (B) comprises a plurality of parallel straight projected line shapes formed by spectrally resolved projections of the straight object line shape (A).
