Abstract

The invention relates to a method and device for collecting spectrometric measuring signals. The aim of said invention is to deliver solutions which make it possible to exactly collect spectrometric measuring signals in a low-cost matter. Said aim is attained by a spectrometric measuring device comprising an input splitting device for passing studied radiation, a Rowland grid device which is associated therewith and reflects incident radiation by spectral spreading, a recording device for recording the narrow part of the spectrum spread by said Rowland grid device and a guiding device which guides and displaces the recording device on a detection path whose spectral clearness is substentially contrast, whereby making it possible to obtain an accurate spectral distribution of studied light in an advantage manner. Said invention also makes it possible to form a recording device or to couple said device to an evaluation system in an operational manner in such a way that possible dependencies of the recorded intensity with respect to the wavelength of the light incident to the recording device are compensated by evaluation procedures. Compensating parameters can determined by gauging procedures and recorded in the internal memory of the device.
