We present a new application of the Nomarski interferometer, to measure the angular position of a parallel laser beam with interferometric precision. In our experimental realization we reach a resolution of 3e-9 rad (6e-4 arcsec) for 1 kHz bandwidth in a 2e-2 rad (1 deg) range. This alternative to the optical lever technique features absolute calibration, independence of the sensitivity on the thermal drifts, and wide range of measurement at full accuracy.
