A radiation generator and a spectrum analyzer capable of changing or adjusting a spectrum are provided. In a radiation generating device for generating electromagnetic radiation having an adjustable spectral composition, a plurality of radiating elements 1, 1a to 1a configured to generate radiating element specific electromagnetic radiations 4a to 4n, respectively, when driven. 1n, including a large number of radiating elements 1, 1a to 1n capable of driving the first radiating element independently of the second radiating element, a spectroscopic element 2, and an optical aperture 3. The spectroscopic element 2 is configured to deflect the radiating element specific electromagnetic radiation 4a-4n according to its wavelength and the position of the radiating element generating the respective radiating element specific electromagnetic radiation, whereby the radiating element specific electromagnetic radiation A specific spectral range can emerge from the optical aperture 3, so that the generated electromagnetic radiation 22 that exits through the optical aperture 3 by selectively driving a number of radiating elements 1 a to 1 n. Spectral composition of can be adjusted. [Selection] Figure 2B |
