  We survey a sample of 32 M5-M8 stars with distance < 40pc for companions with
separations between 0.1 arcsec and 1.5 arcsec and with Delta m_i <5. We find
five new VLM binaries with separations between 0.15 arcsec and 1.1 arcsec,
including a candidate brown dwarf companion. The raw binary fraction is 16%
+8/-4% and the distance bias corrected fraction is 7% +7/-3%, for companions
within the surveyed range. No systems with contrast ratio Delta m_i>1 were
found, even though our survey is sensitive to up to Delta m=5 (well into the
brown dwarf regime). The distribution of orbital radii is in broad agreement
with previous results, with most systems at 1-5AU, but one detected binary is
very wide at 46.8+/-5.0AU. We also serendipitously imaged for the first time a
companion to Ross 530, a metal-poor single-lined spectroscopic binary. We used
the new Lucky Imaging system LuckyCam on the 2.5m Nordic Optical Telescope to
complete the 32 very low mass star i' and z' survey in only 5 hours of
telescope time.
