One-dimensional infrared speckle interferometry has been employed at 2.2 and 3.4 μm for the detection of previously unseen astrometric companions to nearby stars. Thirteen astrometric systems are resolved into two or more components with angular separations from 0.1 to 1.0 arcsec. Masses and absolute magnitudes are derived for the individual components. Companions have been detected in eight additional objects including Lalande 21185.
