Vacuum Tower Telescope (VTT)


Location: Observatorio del Teide, Spain

Owner: Leibniz-Institut für Sonnenphysik (KIS)


The German Vacuum Tower Telescope (VTT) is operated by the Leibniz-Institut für Sonnenphysik (KIS) in cooperation with the Leibniz-Institut für Astrophysik Potsdam (AIP) and the Max-Planck Institute für Sonnensystemforschung (MPS).

It is a classical solar telescope: two coelostat mirrors feed the sunlight into the telescope. The primary mirror has a diameter of 70 cm and a focal length of 46 m. The telescope is inside a building with a height of some 38 m spanning more than 10 floors. The VTT offers several large optical laboratories for all kinds of permanent and temporary optical setups.
