Multi-Object Spectrometer
A multi-object spectrometer is a type of optical spectrometer capable to simultaneously acquire the spectra of multiple separate objects in its field of view. It is used in astronomical spectroscopy and is related to long-slit spectroscopy.[1]
Uses in telescopes
In ground-based instruments
Such instruments are available on most 8-10 meter-class ground-based observatories.[2] For example, the Large Binocular Telescope, W. M. Keck Observatory, Gran Telescopio Canarias, Gemini Observatory, New Technology Telescope, William Herschel Telescope, UK Schmidt Telescope and LAMOST include such capabilities.
Four instruments in the Very Large Telescope, including the KMOS (K-band multi-object spectrograph) and the VIMOS (Visible Multi Object Spectrograph) instruments, have multi-object spectroscopic capabilities.
In space-based instruments
Hubble has been operating the NICMOS (Near Infrared Camera and Multi-Object Spectrometer) from 1997 to 1999 and from 2002 to 2008.
The James Webb Space Telescope's NIRSpec (Near-Infrared Spectrograph) instrument is a multi-object spectrometer.[3]
