Instrumentation and telescopes

Instrumentation and telescopes at the Institute


  • 50 cm Cassegrain Telescope
    The modern Cassegrain reflecting telescope with 50 cm mirror diameter and 5 m focal length is on the roof terrace of the Institute in a dome building with 5.3 m in diameter.
  • Vacuum vertical telescope
    The Siderostat on the roof of the physics building is used for light input into the vacuum vertical telescope (VVT), which is an integrated optical device in the building for high-resolution spectroscopy of the sun and bright stars.
