Specialty highest astronomical telescope on earth

The University of Tokyo Atacama Observatory (TAO) is an observatory on the summit of Cerro Chajnantor , a 5640 meter high lava dome in the Atacama Desert in northern Chile . The observatory is less than 3 miles from the plateau on which the Atacama Large Millimeter Array (ALMA) was built, but is 580 m higher. It is planned by the University of Tokyo .

The observatory is to be equipped with a 6.5 m telescope for observation in the optical and infrared. As a first step, a 1 m pilot telescope, called miniTAO, was installed in 2009; it is the highest observatory in the world. Due to the high location, the limitations of the otherwise existing atmospheric window are overcome and, on the one hand, continuous observations from the visible wavelength range up to 2.5 µm and in a mid-infrared range from 15 µm to over 30 µm are possible.

The future 6.5 m reflector telescope will be built in a Gregory arrangement . The main mirror is silver-plated and the secondary mirror is equipped with adaptive optics to compensate for atmospheric turbulence . The First Light is planned for 2019.
