Abstract
For the imaging of a diode line, a catadioptric objective system is provided. The diode line to be imaged is located between a concave mirror of exactly or approximately spherical shape (possibly with aspherical correction deviating from the theoretical shperical shape) and an objective, usually comprising a plurality of members. One or more surfaces of the objective may be aspherical. The concave mirror produces a reduced image of the diode line on the front focus of the objective.
