Overview of instrumentation


Facility instruments

  • ALFOSC - UV-optical imaging, polarimetry and low-resolution spectroscopy
  • NOTCam - NIR imaging, polarimetry and low-resolution spectroscopy
  • FIES - High-resolution, high-stability optical spectroscopy
  • MOSCA - High-resolution, high-efficiency UV-optical imaging
  • StanCam - Standby CCD imager

Instrumentation with limited access

  • SOFIN - The Soviet-Finnish optical high-resolution spectrograph
  • TURPOL - The Turku photo-polarimeter

Other instruments

  • LuckyCam - High resolution "Lucky" imaging in the visible
  • PolCor - The PolCor "Lucky" Polarimeter/coronagraph

Instrument User Groups

In May 2003 Instrument User Groups have been appointed to advise the NOT Director and STC on the current performance of the instrumentation at NOT, and on the desirability and priorities of instrument upgrades in the short and long term. The Instrument User Groups and their fields of responsibility are:

  • Optical Imaging: Chair: H. Dahle, Oslo (Chair), J. Hjorth (Copenhagen), G. Östlin (Stockholm), and T. Pursimo (NOT)
  • Near-IR Imaging: J. Kotilainen, Turku (Chair), A. Djupvik (NOT) and B. Thomsen (Aarhus)
  • Optical and Near-IR Low-Resolution Spectroscopy: J. Fynbo, Copenhagen (Chair), T. Augusteijn (NOT), and N. Ryde (Uppsala)
  • High-Resolution Optical Spectroscopy: T. Hackman, Helsinki (Chair), S. Frandsen (Aarhus), N. Piskunov (Uppsala), and J. Telting (NOT).
