he Large Millimeter Telescope (LMT), designed by MAN Technologie, is a 50-m diameter single-dish telescope optimized for astronomical observations at millimeter wavelengths (0.85 mm < λ < 4 mm). The LMT Project is a bi-national collaboration between México and the U.S.A. The institutions leading this effort are the Instituto Nacional de Astrofísica, Óptica y Electrónica (INAOE) and the University of Massachusetts at Amherst (UMass) respectively.

A principal scientific goal of the LMT is to understand the physical process of structure formation and its evolutionary history throughout the Universe. More specifically the LMT has the capability to investigate subjects as diverse as the constitution of comets and planetary atmospheres, the formation of extra-solar planets and the birth and evolution of stars, the hierarchical growth of galaxies and clusters and their large-scale distribution, as well as the cosmic microwave background and its anisotropies.
