    Abstract: Methods and systems for carrying out the distribution of light in a ray pathway (21) into wavelength components (21 - 27) comprising optical elements (10, 11) of the diffraction grating type that diffract the said light into several spectral orders (m). The invention is characterised in that at least two diffraction grating surfaces are placed sequentially in the ray pathway whose orientations and grating constants are selected such that the wavelength components that are diffracted at the grating surfaces into the respective orders, whose sum (M = m1 + m2) is constant, emerge from the last grating surface (11) in essentially the same direction.

    Abstract: The invention relates to an optical arrangement, particularly for the use as a main beam splitter and/or beam combiner in a microscope, wherein one or several light rays (11, 12, 15, L1, L2, L3) can be coupled into and one of the coupled light rays (11, 12, 15, L1, L2, L3) can be uncoupled again after passage of the optical arrangement (1, 11). The optical arrangement is characterized in regard to as much a free influenceability as possible of the uncoupled light ray, by having a controllable microstructured element (5), for example a digital micro mirror device (DMD), arranged in the coupled light rays (11, 12, 15, L1, L2, L3), making it possible for beam paths within the optical arrangement (1, 1') to be controllable. Thus the uncoupled light ray/s is/are controllable and/or can be influenced.

    Abstract: An apparatus for carrying out spectral analysis of optical radiation emitted from a light source (11) comprises a spectral detector (1) having an entrance aperture (10) for the radiation from thelight source (11), a first imaging optical component (12), a diffraction grating (14) for wavelength dispersion of the radiation, order sorting means (131, 132) for separation of the spectral orders of the diffraction grating (14), a second imaging optical component (15), and a detecting unit (16) for registration of the light source spectrum divided into order spectra through the order sorting means (131, 132). The order sorting means (131, 132) comprise at least two refractive optical components manufactured from different material. The two refractive optical components (131 and 132) together with the diffraction grating (14) and the imaging optical components (12 and 15) produce a substantially uniform distribution of the order spectra on the detector unit (16). Favourably the order sorting means (131, 132), the diffraction grating (14) and the imaging optical components (12, 15) also co-act to produce a substantially stigmatic image of the entrance aperture (10) in at least one point on the detector unit (16).
