    摘要: In a polychromator, the image plane or the focus line (28) is adapted optimumly to the plane of a detector (26), e.g. to a diode-array. At the same time, an optimum linear wavelength scale is obtained on the detector (26). To this end, an arrangement having a concave grating (14), and an imaging mirror (20) is provided. An optimizing method is described by which both curves can be optimized in converging steps by alternate variation of the distance b between concave grating (14) and mirror (20) and the asymmetry measure G' of the concave grating (14).

    摘要: In a grating spectrometer a signal spectrum is measured repeatedly while inserting different filters. The number of the filters and measurements correspond to the number of the occurring grating orders not suppressed. The signal spectra and the transmission characteristics of the filters are stored. A system of equations is achieved, from which a computer calculates the signal partial spectra associated with the individual grating orders. A total spectrum is composed from these signal partial spectra. Separation of the higher grating orders need not be effected optically, for example by cut-off filters.

    摘要: Polycyclic phthalazines, in particular 2-substituted maduraphthalazines (10,12,15,16-tetrahydroxy-8-methoxy-11-methyl-1,9,14-trioxo-1,2,6,7,9,14-hexahydronaphthaceno-1,2-g-phthalazines), of formula I and their use against gram-positive bacterial strains, particularly against multi-resistant staphylococci (MRSA) and against glycopeptide-resistant, for example vancomycin-resistant, enterococci. The polycyclic phthalazines are thus suitable for preparing anti-bacterially effective pharmaceutical compositions. In formula I, R.sup.1 is carboxyalkyl or carboxyaryl, and R.sup.2 and R.sup.3 represent H or acyl (for example CO-alkyl or COO-alkyl), with R.sup.1 being different from optionally substituted carboxyphenyl when R.sup.3 represents C.sub.1-8 alkanoyl. The invention also relates to salts, amides and esters of compounds of formula I.

    摘要: A monochromator comprises a first and a second concave grating. An entrance slit is imaged by the concave grating in the plane as a spectrum. A disc comprises a spiral slot. A section of the slot forms an intermediate slit periodically sweeping transversely across the spectrum. A concave mirror images the fanning point of the concave grating. Thereby the fanned beams are recombined to a single beam. An exit slit is located in an image plane in which an image of the entrance slit is generated. The spectrum can be scanned quickly and cyclically without the gratings having to be rotated. There is also the effect of a double monochromator. Another embodiment comprises two concave mirrors to generate the image.

    摘要: A pre-monochromator having a grating monochromator includes an unsymmetrically ruled concave diffraction grating, by means of which a light source is directly imaged upon an exit slit. The diffraction grating is unsymmetrical with respect to the distribution of the grating constants such that the image distance remains substantially constant during the rotation of the diffraction grating.

    摘要: Stray light produced in a monochromator by the diffuse reflection of the incoming light beam specularly reflected from the surface of the diffraction grating is practically eliminated by interposing a black glass "absorbent-reflector" in the path of the specularly reflected beam. The small percentage of radiation that is not absorbed by the absorbing glass is reflected to an opposite blackened wall which diffuse reflects an extremely small percentage of the beam back to the absorbent-reflector where a very negligible part is returned to the grating surface and eventually to the monochromator exit slit.
