A stable and inexpensive wavelength reference for precise wavelength calibration of radial velocity spectrographs

Feger, Tobias; Ireland, Michael; Bento, Joao; Bacigalupo, Carlos

Description

We present a stable, inexpensive wavelength reference, based on a white-light interferometer for the use on current and future (arrays of) diffraction-limited radial velocity (RV) spectrographs. The primary aim of using an interferometer is to obtain a dense sinusoidal wavelength reference with spectral coverage between 450-650 nm. Its basic setup consists of an unbalanced fiber Mach-Zehnder interferometer (FMZI) that creates an interference pattern in the spectral domain due to superposition...[Show more]
