Echelle spectrometer calibration by means of laser plasma [PDF]
Spectrochimica Acta, Part B: Atomic Spectroscopy, 2021 Abstract Echelle spectrometers enable the observation of large spectral windows with high resolving power in single recordings. However, these devices are strongly sensitive to temperature variations and even small changes may tamper both the wavelength and the intensity calibration.
