An astro-comb is a sophisticated astronomical instrument that combines the functions of an optical frequency comb and a spectrograph. It is designed to create highly accurate and precise measurements of the spectrum of light from astronomical objects. Optical frequency combs produce a series of evenly spaced, discrete frequency lines (or modes) that can be used as a ruler for measuring optical frequencies with extraordinary precision.
