Key spectroscopy projects

This page covers recent and current projects in spectroscopy.

These are concerned with  

      1.        Design and construction of complete spectrographs or major-subsystems: e.g. 

          2.        Design and construction of Integral Field Units (IFUs) for  Integral Field Spectroscopy

    Fibre-lenslet based IFUs

    • SMIRFS-IFU: Prototype IFU and technology demonstrator for UKIRT, 72 elements, optimized for the near infrared 
    • TEIFU: 1000-element IFU for the 4.2m William-Herschel-Telescope
    • GMOS-IFU: 2 fields of 1000 and 500 elements to enable simultaneous background subtraction. Two built for Gemini North and Gemini South
    • IMACS-IFU: 2 fields of 1000 elements each to enable background subtraction and beam switching. Located at the Magellan-1 6.5m telescope IMACS spectrograph.
    Image-slicing IFUs
    • GNIRS-IFU: 21 slices, IFU for the GMOS spectrograph of GEMINI North.
    • KMOS-IFU: 24 deployable IFUs of 15 slices each, currently in construction
    • JWST NIRSpec IFU: 30 slice IFU for the James Webb Space Telescope's NIRSpec spectrograph, currently in construction

    3. Fibre links and calibration units for Multi-Object Spectroscopy (MOS), e,g. 

    For further information please have a look into our project pages / old project pages.

    4. Enabling technology

         This is supported and underpinned by research and development programmes in

    making use of CFAI's extensive facilities for metrology, fibre system assembly, precision optics manfacture and assembly, integration and verification.
