Echelle spectrometers and charge-coupled devices
Spectrochimica Acta Part B: Atomic Spectroscopy, 1997Abstract 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

Considerations for Designing an Echelle Spectrometer
2014After 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.

An echelle diffraction grating for imaging spectrometer
SPIE Proceedings, 2016We demonstrate an echelle diffraction grating (EDG) of 17 input waveguides and 33 output waveguides. For each input waveguide, only 17 of 33 output waveguides are used, receiving light ranging from 1520 nm to 1600 nm wavelength. The channel spacing of the EDG is 5 nm, with loss of -6dB and crosstalk of -17dB for center input waveguide and -15dB for ...

An Echelle Spectrometer–Spectrograph for Astronomical Use
Applied Optics, 1967A compact echelle spectrometer-spectrograph has been designed for use at the Cassegrain focus of the University of Wisconsin 91-cm telescope at Pine Bluff. Laboratory results obtained with this instrument show that it has great potential for both stellar and nebular studies. Typical photographs and photoelectric scans of laboratory spectra are shown. A

Simple spectral reduction algorithm used for the echelle spectrometer
Applied Optics, 2018The 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, 2017Echelle 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, 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

A Low Cost Spectrographic Attachment for an Echelle Spectrometer
Applied Spectroscopy, 1983The 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.

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 ...
