    Abstract: The invention concerns an optical device (100) comprising:
    - a fibre array (120) comprising input elements (122) positioned on an emission line (112), and output elements (121) positioned on a reception line (111), parallel to the emission line (112) and separated by a distance D and,
    - a compact dispersing system (130) ensuring wavelength selective conjugation of signals between the end faces of the input elements (122) and the end faces of the output elements (121) and comprising:
    - a plane mirror (140)
    - a concave mirror (60), and
    - a plane diffraction grating (50)


    The optical device (100) being characterised in that the size of the plane mirror (140) is limited with respect to the two said parallel straight lines (111, 112) such that beams picopagating from the end faces of the input elements (122) to the concave mirror (60) and beams propagating from the concave mirror (60) to the end faces of the output elements (121) are not affected by the presence of the plane mirror (140).

    Abstract: An optical spectrum analyzer (20) measures to-be-measured light while carrying out calibration processing for correcting wavelength information of spectrum data of the to-be-measured light by a wavelength information correction device (56) through a storage device (58) based on the spectrum data of reference light that is obtained by causing the reference light whose wavelength is known to be incident on a tunable wavelength filter (25) from light incident devices (21, 22) at all times together with the to-be-measured light. Since the optical spectrum analyzer (20) can continuously measure the to-be-measured light in a wide wavelength range at high speed while maintaining high wavelength accuracy, it can continuously obtain the spectrum data of the to-be-measured light with high wavelength accuracy even if it is installed in a place in which an environment intensely changes.
