Abstract:
1. A highly sensitive spectrum analysis unit with a diffraction grating; wherein a parallel light bundle having a wavelength range impinges on the diffraction grating which splits the different wavelengths into spectra by diffraction in first directions; wherein wavelength partial ranges of the spectrally split light bundle can be focused on a detector row by means of camera optics; and wherein evaluation electronics are connected to the detector row and acquire the generated spectrum as information and display it; wherein the light bundle passes through a first optical clement, and then wavelength partial ranges of a spectrally split light bundle impinge on respective partial regions of the diffraction grating; wherein the diffraction grating has the same grating constant across all partial regions and a changing profile shape; and wherein the profile shapes generate different blaze wavelengths that lie in the respective wavelength partial ranges.
