Echelle spectrograph pdf

WebThe paper presents a method for calculation of the main paraxial and energy parameters of a high-resolution astronomical spectrograph with a single echelle grating in a wide spectral range, without cross-dispersion elements. We consider two variants of the system design, namely, with a fixed grating (spectrograph) and with a movable grating (monochromator). WebThe SE 200 is an echelle-type spectrograph that represents a different approach to spectrograph design for use with 2-dimensional CCD imaging arrays. Scanning a grating to cover a wide wavelength range is a thing of the past. The SE 200 achieves high spectral resolution over the entire wavelength range of the CCD with no moving parts.
