High-contrast imaging instrumentation has greatly advanced over the last two decades and two of the NASA-commissioned large studies (LUVOIR & HabEX) include an instrument to image and characterize exo-Earths. This paper describes the status and goal of 8 optical testbeds currently in operation to experimentally validate the necessary technologies.
