    Abstract: The invention relates to an optical module for the wavelength reference measurement. The inventive module is essentially provided with an optical waveguide (7) having an integrated fibre Bragg grating (8) which is provided with a transmission maximum at a desired wavelength. A photodetector (10) for receiving the measuring radiation bundle that has penetrated the fibre Bragg grating (8) is arranged downstream in relation to the fibre Bragg grating (8). A reference radiation bundle can be produced by means of a beam splitter (5) if desired. Said bundle is detected in an additional photodetector (6).

    Abstract: The method involves operating a light transmitter (8) and setting the relative position between two parts (22,23) of a receptacle (2), the first part comprising a deflection mirror, and the second part acting to hold an optical fibre. The position is adjusted so that the emitted beam falls on the deflection mirror and lands in the centre of the optical fibre. The relative position of the first part and the light transmitter is then determined, and the second part is adjusted with respect to the first part to fulfil predetermined conditions relating to the position of the optical image plane of a lens (12,40) with respect to the front face of the optical fibre.
