    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.

    Abstract: The conventional grating is substituted by one or more curved prisms in a concentric spectrometer of the type derived from the Offner mirror objective. The curved prisms are known as Fery prisms. The deviations from the concentric form are used as a corrective device. The spectral apparatus is especially suited as an imaging spectrometer having a detector array because the two-dimensional image can be formed in the direction of the spatial coordinate as well as the spectral coordinate without distortions and curvatures.

    Abstract: A multi/demultiplexer is disclosed wherein the light-conducting fibers are cemented into a perforated plate made of a photolithographically etchable material, and their terminal faces are ground down and polished together with the surface of the perforated plate. To compensate for focusing differences, a plate of appropriately matched thickness is disposed between the transparent supporting block and the surface of the perforated plate.
