    Abstract: The invention concerns an optical system for use in spectrometry and/or endoscopy, in which at least one probe is exposed to directional radiation produced by a radiation source, the radiation emanating from the probe is led to a spectrometer, in particular a simultaneous spectrometer, and or to an imaging device. It is proposed that the optical system should be provided with at least one control device with a radiation inlet surface and a radiation outlet surface; the control device should be provided with control elements (24) held by a frame and capable of being displaced from a first position in such a way that the radiation energy transferred from the radiation inlet surface to the radiation outlet surface can be controlled while leaving the radiation outlet aperture substantially unchanged. In addition, or alternatively, the optical system is provided with at least wavelength selection unit which has at least one dispersion element element for spectral splitting of the radiation passing through at least one inlet slit and impinging on the dispersion element; and with at least one optical waveguide. The dispersion element and/or a focusing element focus the spectrally split radiation onto a focal surface and the optical waveguide receives a predetermined range of the spectrally split radiation in the focal surface.

    Abstract: In a spectroscopic system, esp. employing a simultaneous spectrometer, an aperture changer (14,15) is provided for optical energy transmission in the direct space (8), between the light source (I) or its image (L') and the sample (9) and between the sample (9) and the inlet gap (3) of the spectrometer. Each aperture changer (14,15) consists of a , conical waveguide or mirror with light entry and exit openings, the larger of which faces the sample (9). The sample ( is accommodated in a capillary cell arranged on the optional axis the aperture changers (14,15) such that light passes through it along its longitudinal direction. Also claimed are (i) a micro-cell system for absorption photometry, esp. in the above system; (ii) use of the above micro-cell system in the above spectroscopic system, in absorption spectrometry esp. of weakly absorbent liquids and in high pressure liq. chromatography; and (iii) a spectroscopic system including the above micro-cell system.

    Abstract: A microcuvette system for absorption photometry contains a cylindrical cuvette tube (1) having a hollow core for holding a sample liquid (2) through which radiation is passed at least in a longitudinal part of the hollow core, the absorption of which radiation is subsequently measured. The cuvette tube (1) and the sample liquid (2) are coordinated in terms of refractive index so that they act as a stepped waveguide for the radiation, in which waveguide the sample fluid (2) forms the core and the wall of the cuvette tube (2) forms the cladding, so that the radiation undergoes multiple reflection, preferably multiple total internal reflection, at the outer wall of the cuvette tube (1) and the radiation passes through the sample fluid many times.
