Abstract
The optical schemes of high numerical aperture spectrographs based on concave
holographic diffraction gratings are described. A calculations of an optical schemes
using flat field spectrograph method for analyzing the fluorescence of all kinds of Quantum
dots in a wide range of wavelengths with spectral resolution of 6,3 nm are submitted.
A special calculation of spectrographs for investigating CdSe/ZnS, InP Quantum
dots with high resolution of 1 nm are given because of their wide uses.
An experimental mounting for analyzing Raman scattering in carbon nanotubes is
described. Experimental results are given. On the basis of these results the requirements
for optical characteristics of a compact specialized spectrograph for analyzing Raman
scattering in carbon nanotubes are developed. The calculation of an optical scheme
using flat field spectrograph method with spectral resolution of 3.5 cm-1 is submitted.
