The Space Nanotechnology Laboratory (SNL) at MIT conducts research on nanofabrication, nanometer-accuracy x-ray optics fabrication, assembly and metrology, ultra-high resolution lithography, nanometrology, and nano-accuracy diffraction grating fabrication. SNL's pride and joy is the world's most advanced grating patterning tool, the Nanoruler -- a ruler with "ticks" only a few hundred billionths of a meter apart. Applications for the Nanoruler (patent pending) might include the manufacture of computer chips and space physics. More information, including images and a White Paper describing the Nanoruler, are available from this website. The website also provides a history of the Laboratory, a description of other projects, and an extensive list of papers, many of which are short and available online.
