Realization of a compact cross-grating spectrometer and validating experimental tests

open access: yes, 2022
S.1338-1346Echelle inspired cross-grating spectrometers offer the potential to bridge the gap between classical high-end echelle spectrometers and curved-grating single-element instruments. In particular, the cross-grating approach offers the possibility

Cross-Order Echelle Grating Triplexer Based on Amorphous Silicon Nanowire Platform

open access: yes, 2008
We present fabrication and measurement results of an ultracompact silicon-on-insulator-based echelle-grating triplexer, which uses different diffraction orders to cover a large spectral range from 1.3 mu m to 1.5 mu m, with a footprint of 150 mu m x 200 ...

The immersed echelle - I. Basic properties

open access: yes, 1999
High-resolution spectrographs for very large telescopes lead to new challenges in grating technology to achieve optimum matching of the slit width to the seeing disc. This has led elsewhere to the development of long echelles of high blaze angle produced

Compact high-resolution spaceborne echelle grating spectrometer with acousto-optical tunable filter based order sorting for the infrared domain from 2.2 to 4.3μm

open access: yes, 2016
A new compact spaceborne high-resolution spectrometer developed for the European Space Agency's Venus Express spacecraft is described. It operates in the IR wavelength range of 2.2 to 4.3 (μm and measures absorption spectra of minor constituents in the ...

Modeling echelle spectrographs

open access: yes, 1997
A generic description of spectrographs based on first optical principles is developed. It incorporates off-plane grating equations and rotations in three dimensions in order to adequately account for line tilt and order curvature.
