Optical characterisation and modelling of a UV-Vis Fabry-Perot etalon for wavelength calibration of EPRV spectrometers
Stable broadband Fabry–Pérot etalons are essential calibrators for extreme-precision radial-velocity (EPRV) spectrographs, providing dense, uniform reference spectra with the line symmetry and long-term stability required to achieve centimeter-per-second sensitivity. The ultimate spectral stability and uniformity of th...
