The search for extrasolar planets places a very high demand on the precision of calibration sources. At NIST, we have characterized several new (and old) calibration systems for astrophysical spectrometers. These include hollow cathode emission lamps, molecular gas absorption cells, and a fiber-based Fabry-Prot interferometer. I will discuss these sources and their potential application to current and future astrophysical spectrometers.
