The paper describes an apparatus for investigating Raman scattering in carbon nanotubes. Experimental results are presented. Based on these results, the requirements on the optical characteristics of a specialized compact spectrograph for analyzing carbon nanotubes are worked out, and an optical layout is designed, using a technique for designing a flat-field spectrograph. The proposed spectrograph provides a spectral resolution of 3.5 cm<sup>−1</sup>.
