Echelle-emission spectrometer with divided spectral coverage
Optics and Precision Engineering, 2014Limited by the development of detectors, the Inductively Coupled Plasma Atomic Emission Spectrometry(ICP-AES) based on an echelle spectrograph is difficult to complete the multiple element measurement at a wider spectral coverage. This paper focuses on the improvement of an existing echelle spectrograph. It designs a new wider band echelle spectrograph

Echelle spectrometer for single shot elemental analysis
SPIE Proceedings, 1990The paper presents a spectrometer combining echelles with imaging detectors and optimizing the echelle design to match the behavior of the detector, to be used for simultaneous high-resolution multiwavelength observations of a variety of discharges. The instrument utilizes a dual Czerny-Turner mount, with compensation of astigmatism generated in the ...

Spectral Efficiency of the SpectraSpan III Echelle Grating Spectrometer
Applied Spectroscopy, 1985The efficiency of an echelle grating spectrometer incorporating prism cross-dispersion is empirically evaluated over a broad wavelength range incorporating a large number of orders. A derived parameter, the spectrometer efficiency, proportional to the spectrometer luminosity, conveniently gauges dynamic features of the echelle efficiency ...

Optical Design of the ARC Echelle Spectrometer
1988The high-dispersion spectrometer for the ARC 3.5-m telescope combines an echelle with prism cross-dispersion in an in-plane arrangement. This spectrometer will be located at an f/10 Nasmyth focus with an off-axis paraboloidal collimator and an f/2.7 Schmidt camera with achromatic corrector and CCD detector.

The performance of a large echelle grating in a solar spectrometer
Solar Physics, 1967A number of tests of a large diffraction grating are described. It is shown that useful information about the performance of the grating in a spectrometer can be obtained from an analysis of the diffracted wavefront by the method of Stroke. Comparison of the instrumental profile at three wavelengths strongly suggests that the influence of changes in ...

The Multi-Echelle Grating Arrangement (Mega) Spectrometer
SPIE Proceedings, 1984A spectrometer system, based on the Multi-Echelle Grating Arrangement (MEGA) (1) has been developed. Through series diffraction in an even number of echelle gratings, high dispersion and spectral resolutions are obtained. It can be shown (1) that with n gratings of width W, utilized in a MEGA-spectrometer of focal length f, the same resolution and ...

Figures of merit for an ICP-echelle spectrometer system
Spectrochimica Acta Part B: Atomic Spectroscopy, 1982Abstract Figures of merit of an ICP-echelle Spectrometer System are presented for 55 elements. The analytical importance of each figure of merit is discussed. The analytical results obtained with the ICP-echelle system compare well with previously published figures for ICP studies.
