Use of solid fused silica etalon with broadband metallic coatings for calibration of high-resolution optical spectrograph
Supriyo Ghosh, William Martin, Kajal Kunverji +1
Wavelength calibration is a key factor for high-resolution spectroscopic measurements for precision radial velocities. Hollow-cathode lamps (e.g., ThAr), absorption cells (e.g., io…
