We report on a high resolution inelastic UV scattering table-top setup conceived for Brillouin mea- surements. The system is based on a tandem 1+1 pass scanning Fabry-Perot interferometer of Sander- cock type. Special optics were used in order to adapt such an interferometric device, nowadays only used at visible or IR wavelength, to the UV range. The advantages with respect to other UV Brillouin scattering instruments are the larger resolving power and the improved contrast in the low frequency spectral region. To corroborate these features we provide a comparison between data obtained using the described system and those from existing UV Brillouin scattering instruments.

Abstract
We report on a high resolution inelastic UV scattering table-top setup conceived for Brillouin mea- surements. The system is based on a tandem 1+1 pass scanning Fabry-Perot interferometer of Sander- cock type. Special optics were used in order to adapt such an interferometric device, nowadays only used at visible or IR wavelength, to the UV range. The advantages with respect to other UV Brillouin scattering instruments are the larger resolving power and the improved contrast in the low frequency spectral region. To corroborate these features we provide a comparison between data obtained using the described system and those from existing UV Brillouin scattering instruments.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
