SOAR (SOuthern Observatory for Astrophysical Research) Telescope is a 4.1 m diameter alt-az optical telescope constructed by a consortium of the Brazilian Ministry of Science, the National Optical Observatories, the University of North Carolina and Michigan State University. It is located at Cerro Pachon, in Chile, and was designed to work from the atmospheric cut-off in the blue (320 nm) to the near infrared, to have excellent image quality (0.22 arcseconds), fast slewing and to have up to nine instruments mounted ready for use. Its primary mirror is only 10 cm thick and is supported by 120 eletro-mechanical actuators, to set and hold its optimum shape. The tertiary mirror will partially correct the atmospheric turbulence by tip-tilting at 50 Hz.
