Abstract

A device for separating radiation beam components of different wavelengths, which issue from an optical fibre by means of a reflection grating (13) and wavelength selective mirror (12) which permits beam components whose wavelengths are comparatively similar to be separated from each other and from those wavelengths substantially different therefrom. A wavelength-selective mirror (12) is arranged between the input optical fibre (10) and the reflection grating (13), which mirror reflects the radiation beams of wavelengths lambda N+1 which are substantially different from the wavelengths lambda 1... lambda N of a group of radiation beams of comparatively similar wavelength to an output fibre (20), via lens (15) and dichroic filter (14) which serves to suppress any radiation of wavelength lambda 1... lambda N also reflected by mirror and transmits the radiation beams of comparatively similar (closely spaced) wavelength to the reflection grating 13 which reflects each wavelength at a different angle ( theta 1... theta N) and effects spatial separation of the constituent wavelengths which are then focused onto output fibres (1, 2...N) via lens (31). <IMAGE>
