AXIAL SPECTROMETER WITH HIGH SPATIAL AND SPECTRAL RESOLUTION AND VARIABLE SPECTRAL OBSERVATION DOMAIN

摘要

The axial spectrometer has a point source (3,31,...39) which sends a luminous beam (2,21,...29) to a first optical element (1). The first optical element collimates the beam to a grism (4) with a dispersion axis and to a second optical element (5) which focuses the dispersed beams (9,91,92,...99) on to a means of detection (6). Each point source defines a central wavelength in the focal image plan of the second optical element Independent claims are also included for the following: 1) A Raman type spectroscope which includes the high resolution axial spectroscope 2) A photoluminescence type spectroscope which includes the high resolution axial spectroscope 3) A fluorescence type spectroscope which includes the high resolution axial spectroscope
