    Abstract: The present invention refers to an arrangement ('C') adapted to evaluate the spectral intensity of and/or a changing in the spectral intensity of an electro-magnetic beam (1) or a bundle of beams (2), whereby said bundle of beams is directed towards and received by a lens element (3a) and where said lens element (3a) is adapted to direct said bundle of beams towards a multitude of electro-magnetic beam to an electric signal transforming means (4), named as an opto-electric transforming means, said means adapted to generate an electric signal (5) representative to said spectral intensity of or said changing in said spectral intensity of said beam (1, 2). The invention suggests that a multitude of lens elements (3, 3a) shall expose dimensions adapted within a sub-micron scale (10-6m) and that at least one of said opto-electric transforming means (4), preferably a multitude of said means (4), is arranged adjacent to said lens element (3a).

    Abstract: A rotary spectrometer including a plurality of input ports. Each input port may be arranged to receive an optical waveguide carrying electromagnetic radiation. The spectrometer also includes a plurality of optical bandpass filters, which are housed on a first body that rotates under the control of a motor so that each optical bandpass filter may be brought into alignment with each input port. Further, the spectrometer includes a plurality of detector circuits disposed on a second body that rotates with the first body. Each detector circuit is optoelectrically coupled to one of the plurality of optical bandpass filters, thereby resulting in each detector circuit being dedicated to responding to a range of wavelengths determined by the bandpass filter to which it is optoelectrically coupled.
