Echelle spectra

WebOct 31, 2024 · Echelle grating provides high spectral resolving power and diffraction efficiency in a broadband wavelength range by the Littrow mode. The spectrometer with the cross-dispersed echelle scheme has seen remarkable growth in recent decades. Rather than the conventional approach with common blazed grating, the cross-dispersed … WebThe echelle grating is designed to operate in multiple orders to produce high-resolution spectra. In contrast to normal gratings, echelles are ruled at 30–300 grooves per millimeter by ion bombardment, and are frequently in the range of 30–120 orders. The grating consists of saw-like grooves varying in height and 6–13 μm in depth. The ...
