“…The echelle and cross-dispersion spectroscopic scheme is used by many high-end analytical instruments, including ICP-OES [14][15][16][17][18], AAS [19,20], and LIBS [21][22][23]. The spectral resolution is up to the picometer scale, and the wavelength covers the range from deep ultraviolet to near-infrared light.…”

Echelle grating provides high spectral resolving power and diffraction efficiency in a broadband wavelength range by the Littrow mode. The spectrometer with the cross-dispersed echelle scheme has seen remarkable growth in recent decades. Rather than the conventional approach with common blazed grating, the cross-dispersed echelle scheme achieves the two-dimensional spatial distribution of the spectrum by one exposure without scanning in the broadband spectral range. It is the fastest and most sensitive spectroscopic technology as of now, and it has been extensively applied in commercial and astronomical spectrometers. In this review, we first highlight the characteristics of the echelle and then present the optical layout, detection approach, and method of calibration. Finally, we discuss the state-of-the-art implementations and applications of commercial and astronomical instruments.

Enabling orders of magnitude sensitivity improvement for quantification of Ga in a Ce matrix with a compact Echelle spectrometer

Abstract: Chemical analysis of lanthanide materials via laser-induced breakdown spectroscopy (LIBS) is often hindered by the complex spectral response and self-absorption phenomena that occur in the LIBS plasma. Previous attempts to...
