OSIRIS (astronomy)

from Wikipedia, the free encyclopedia

OSIRIS is the name of currently three completely independent astronomical instruments. The duplication of the naming is accidental and arose from an attempt by two scientific teams to create acronyms for similar terms .

OH-Suppressing Infrared Integral Field Spectrograph

OSIRIS (OH-Suppressing Infrared Integral Field Spectrograph) is an infrared - spectrograph for the Keck II telescope at the Keck Observatory in Hawaii . OSIRIS records spectra in the near infrared with a narrow bandwidth and thus enables image sequences at different wavelengths. The instrument enables astronomers to mask out wavelengths in which the earth's atmosphere outshines the recordings, thus enabling the detection of objects that are 10 times weaker than previously possible.

Optical System for Imaging and low Resolution Integrated Spectroscopy

Along with CanariCam, OSIRIS (Optical System for Imaging and low Resolution Integrated Spectroscopy) is one of the first instruments of the Spanish Gran Telescopio Canarias (GTC) large telescope . With its sensitivity in the wavelength range from 365 to 1000 nm, OSIRIS is a multi-purpose instrument and can be used for image display as well as multi-object spectroscopy (MOS) with low resolution. OSIRIS will mainly be used for the OTELO (OSIRIS Tunable Emission Line Object) investigations.

Optical, Spectroscopic, and Infrared Remote Imaging System

OSIRIS (Optical, Spectroscopic, and Infrared Remote Imaging System) is the scientific camera system on board the Rosetta spacecraft launched by ESA in March 2004 . It was constructed under the leadership of the Max Planck Institute for Solar System Research .
