Problems solved by technology

However, this approach is ruled out when using UV flash lamps, since typically the flash pulse duration of 1 ns and below is much smaller than the minimum adjustable exposure time of the CCD detector, and may be due to the only possible low flash pulse repetition rate , there are usually no exposures of more than one flash pulse

Embodiment Construction

[0055] In the drawings, the same features are identified with the same reference signs. In the following, the "left and right" axes will be designated as

[0056] The claimed spectroscopic measurement system is marked in its entirety with the reference numeral 1 and is shown in FIG. 1 .

[0058] The light from the light source 2 is collimated (collimated) for example by a lens 10 and radiated through the sample 9. as collimated

[0059] The lens 10 directs the light onto the entrance aperture 7 of the spectrometer for detection. As an alternative to using a single lens 10

[0061] Light from the light source is radiated through the entrance aperture 7 in the direction of the imaging system 8a. The aperture 7 is oriented along the z-axis. light shape

[0063] The detector 3 is designed as a two-dimensional (2-D) detector. Thus, detector 3 is an array of detectors oriented on the x‑y axis

[0064] In one embodiment, the detector 3 is tilted relative to the x-z axis, in particul...

Abstract

The invention discloses a spectroscopic measuring device (1) for a measuring point of a process automation system, comprising: a broadband light source (2) for radiating light through an entrance aperture (7) onto a sample to be measured (9), wherein The beam of light forms an illumination plane (x-y); a light limiter (5), which limits the light to an angle, in particular 90°, to said illumination plane (x-y), thereby producing different amounts of light; a dispersion element (4) for separating light according to the wavelength of the light; and a detector (3) for receiving the light separated according to the wavelength of the light, wherein the light source (2) sends the light Light is directed through the sample (9) towards the entrance aperture (7), the limiter (5) and the dispersive element (4), and the light hits the detector (3), wherein the detector (3) is designed is a two-dimensional detector and is oriented such that light can be received at said angle, ie in particular 90°.

Description

Spectral measurement device technical field [0001] The present invention relates to a spectroscopic measurement device for a measurement point of a process automation system. Background technique During production, spectroscopic measurements can be performed in gases, liquids, solids and multiphase mixtures to obtain relevant The result of a substance (in particular the quantity or quality of the substance) formed in a production process or as a product of a process. Spectroscopically amount, the value of the measurand related to the concentration of educts and / or auxiliary materials of the process can be obtained. For example, in biological During chemical production, the concentration of nutrients and / or metabolites of microorganisms used in the production process can be and / or the concentration of products produced in the process medium in the process is monitored, and the process is controlled and / or by means of The measurement data thus obtained are adjusted...
