Considerations for Designing an Echelle Spectrometer

2014
After we had “captured” the echelle grating and the corresponding collimator mirror from the internet, these parts were still not sufficient for the construction of a complete echelle spectrograph. The cross-disperser, the camera optics and the slit assembly at the grating rack were missing. The seller was called.

Echelle spectrometers and charge-coupled devices

Spectrochimica Acta Part B: Atomic Spectroscopy, 1997
Abstract State-of-the-art spectrometers are equipped more and more with solid-state array detectors for the recording of spectra. The basis of this development is the tremendous improvement in the performance of detectors. The photometric parameters of individual pixels of detectors (quantum efficiency, dark current, read-out noise) are comparable to

Simple spectral reduction algorithm used for the echelle spectrometer

Applied Optics, 2018
The structure of the echelle spectrometer equipped with a prism cross-dispersion element is very complex because of the nonlinear interaction between the prism and the echelle grating, which makes it difficult to extract the wavelength information from the two-dimensional spectrogram.

A design cycle for echelle spectrometers

International Optical Design Conference 2017, 2017
Echelle spectroscopy is a mature technique that was introduced over 60 years ago. However, the process of determining all of the physical parameters of an echelle spectrometer, especially the main parameters of the echelle grating itself (the groove density, the blaze angle, and the grating’s size), is not easily found in the literature.

Echelle-emission spectrometer with divided spectral coverage

Optics and Precision Engineering, 2014
Limited 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, 1990
The 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 ...

A Low Cost Spectrographic Attachment for an Echelle Spectrometer

Applied Spectroscopy, 1983
The report describes a simple, low cost photographic attachment for an echelle spectrometer. The crossed dispersion prism/echelle grating system provides a high resolution spectrum in a compact two dimensional format. It has been estimated that the echelle spectrum obtained on a 4 by 5 in.

Optical Design of the ARC Echelle Spectrometer

1988
The 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.

Figures of merit for an ICP-echelle spectrometer system

Spectrochimica Acta Part B: Atomic Spectroscopy, 1982
Abstract 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.
