Abstract:
The possibility of using a diffraction lens as a simple imaging spectrometer was demonstrated. Spectral images for white, red and green LEDs were experimentally generated on the basis of a sequence of images obtained by scanning along the optical axis. A comparison of the obtained spectral distributions with the integrated spectra of the LEDs under study was conducted. The error was found to vary from 8 to 13%.

Keywords:
imaging spectrometer, diffraction lens, spectrum, inverse problem.
