    Abstract: An optical system and method comprising a diffraction grating which consists of diffracting elements spaced from one another by unequal distances. Correction of residual defocusing in the image produced by such a grating is accomplished by translating it along its surface. As one embodiment, a monochromator is constructed in which a self-focusing grating scans the value in wavelength which is transmitted between fixed slits by rotation of the grating about an axis fixed in space. Combined with a translation of the grating along its surface, such a monochromator produces a symmetrical image exactly in focus at the exit slit for all scanned wavelengths.

    Abstract: An optical device for the spectral analysis of a light source comprises

    a) a spectrograph assembly (1,2,31,32) including a dispersive element (32), and
    b) a classical collimator (3),
    the device being characterised in that the spectrograph assembly (1,2,31,32) supplies a complete intermediate spectrum at the object focus of the classical collimator and the classical collimator (3) reforms, at its image focus, an image of the dispersive element (32).
    The spectrograph assembly (1,2,31,32) is preferably a Czerny-Turner or other type of spectrograph comprising an entry slit (31), two juxtaposed concave mirrors (1,2) of the same focal length and a dispersive element (32) placed strictly in the common focal plane of the two mirrors (1,2). Most preferably, the classical collimator (3) is the first mirror of a second, similar spectrograph assembly (3,4,34).
    The device is most advantageous in that it is readily useable for both simultaneous and sequential spectroscopy.
