The Multi-Echelle Grating Arrangement (Mega) Spectrometer

SPIE Proceedings, 1984
A 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 ...

GIANO: An Ultra-Stable IR Echelle Spectrometer for the TNG Telescope

2006
GIANO is an IR cross-dispersed echelle spectrometer designed to achieve high throughput, high resolving power, wide band coverage and high accuracy radial velocity measurements. It also includes polarimetric capabilities and a low resolution mode that make it a very versatile, common user instrument which will be permanently mounted and available at ...

The performance of a large echelle grating in a solar spectrometer

Solar Physics, 1967
A 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 ...

[Algorithm for Background Removal in Spectral Image of Echelle Spectrometer].

Guang pu xue yu guang pu fen xi = Guang pu, 2018
Echelle spectrometer gets full spectrum by transient direct reading because of the characteristic of cross-dispersion. The two-dimension spectra received by flat-plane detector needs to be reduced to one-dimension spectra so that the effective wavelength can be detected.
