Abstract
A transparent carrier body of a diode-array spectrometer having a concave grating is configured as a biconvex lens and the diode array is mounted at a distance (d) to a second convex surface lying opposite the concave grating. Preferably, the radii of curvature (r.sub.1, r.sub.2) differ from each other only slightly. A simplified manufacture and adjustment is possible with good optical correction.
