Nulling interferometry has been proposed for the direct detection of Earth-like planets. Deep stable nulls require careful control of the relative intensity and phase of the beams that are being combined. We present a novel compensator, the Adaptive Nuller, that corrects the intensity and phase as a function of wavelength from 8 to 12 (mu)m using a deformable mirror. This compensator has been used to produce rejection ratios of 82000:1 over a bandwidth of 3.2 (mu)m centered around 10 (mu)m.
