    • The invention relates to a transmission spectrometer for analysing a liquid sample with regard to a medically significant component, in particular a bodily fluid, preferably in the middle infrared spectral range MIR. Said spectrometer comprises: a cell (3) with opposing transparent walls (4, 5) for holding the sample; a light source (2) for emitting radiation, which passes through the opposing walls (4, 5) of the cell (3) and is partially absorbed by the sample; a plurality of filters (8a-8p) that are arranged on one of the walls (5) of the cell (3) and that are respectively permeable to a wavelength range, in which the medically significant component of the sample causes absorption maxima; a plurality of detectors (9a-9p), which are respectively associated with one of the filters (8a-8p), for detecting the intensity of the radiation that passes through the cell (3) and the respective filter (8a-8p); and an evaluation unit (10), which is connected to the detectors (9a-9p) and determines an analytical result from signals that are generated by the detectors (9a-9p) in accordance with the detected intensity. According to the invention, one of the opposing walls (5) of the cell (3) supports the detectors (9a-9p).

    • A radiation arrangement suitable for emitting IR radiation has a flat radiation source (2), the radiation emitted from which is deflected in at least one predetermined direction by a reflector (4); said reflector consists of a body, the circumference of which becomes smaller towards the beam outlet and the reflective surface of which is substantially surrounded by the radiation source; in an axisymmetrical arrangement, the distance between the radiation source and the axis of the reflected beam is greater than the radius of the reflector component arranged symmetrically in rotation along the optical axis. The radiation body may consist thereby of a resistive coating (2) on an electrically insulating substrate (3) or a self-supporting resistive strip or wire. An essential advantage here is that there is a relatively large area for the generation of IR radiation which can be bunched into a high-intensity beam by the reflector arrangement, as is necessary in measuring instruments, e.g. gas analysers.
    • 适于递送红外辐射辐射组件的装置包括一维地形成辐射源(2),通过反射器射出的辐射(4)至少在预定的方向偏转; 所述反射器由主体形成,其的周边在射线出口,并且其反射面是由辐射源所包围的主要部分的方向上减小; 在轴向对称的布置中,从反射光束的轴的辐射源的距离比沿所述反射器元件的光轴对称地设置在旋转的半径大。 散热器本体可以由一个沉积在电绝缘基板(3)上的电阻层(2)或自支撑阻力带或电阻丝。 主要优点是可以看到在一种代表红外辐射的产生,一个比较大的空间是可用的,其可以由反射器装置来捆绑成一个高强度的光束,如在测量仪器如气体分析仪是必需的。
