摘要： An echelle spectroscope has one or more echelle diffraction gratings, one or more elements for separating dispersed light into portions corresponding to different orders of diffraction and one or more imaging means such as imaging mirrors but there is only one image detector. These components are so designed and arranged with respect to one another that the total range of wavelength to be analyzed is divided into a plurality of smaller ranges and the portions of the spectral light from a source corresponding to different ones of these divided wavelength ranges travel on different paths but would each form an image on the same image detector. A shutter is provided so as to selectively allow one of these portions of spectral light corresponding to one of different wavelength ranges to pass through.
