Abstract: Spectrometer device (100) with entrance aperture (2), diffraction grating (3), two detectors (5a, 5b) to spectrally measuring the incoming light (L), the detectors being located on the same side of the dispersion plane. Two vertically focusing mirrors (4, 4a, 4b) focus the light onto detectors, the minors being arranged as front row mirrors (4b) and back row minors (4a) along two polygon graphs (6a, 6b) offset to each other and to the focal curve. The angles of deflection (cp, 91) for the front row mirrors are <90°, allowing to minimize the offset (dl) of the front row minors (4b) to the focal curve. The distances (d) between the front row minors and corresponding detectors (5b) is minimized while still avoiding collisions between the detectors (5b) and their mounts with back row detectors (5a) and their mounts. The front row mirror elements are overlapping the adjacent back row mirror element.

Abstract: Disclosed is a method for producing polyalcohols in the form of sugar alcohols from the group comprising sorbitol and mannitol and other optional C2 to C6 polyols. According to said method, a monosaccharide, disaccharide, oligosaccharide, or polysaccharide containing at least one glucose unit and/or at least one fructose unit is continuously reacted with hydrogen at an elevated temperature and at a great pressure in an aqueous phase in the presence of a hydrogenating catalyst based on ruthenium or ruthenium oxide so as to obtain the inventive polyalcohols. The minimum temperature is set at 100° C. while the minimum pressure is set at 150 bar and the maximum dwell time of the reactants during catalytic hydrogenation is set at 600 s.
