Brillouin TFP-1 Scattering Interferometer

The Tandem Fabry-Perot Interferometer is intended primarily for the study of Brillouin spectra, particularly of many, or broad, features over an extended spectral range. The flexibility is such that even Raman spectra (out to about 500cm-1) may be measured. The novel construction allows a change of mirror spacing without more than minor loss of alignment, so that full alignment may be achieved again within seconds.
