VISIR - VLT Imager and Spectrometer for mid Infrared
The VLT spectrometer and imager for the mid--infrared (VISIR) was built by CEA/DAPNIA/SAP and NFRA/ASTRON, and is located at the Cassegrain focus of UT3. It provides diffraction-limited imaging at high sensitivity in the two mid infrared (MIR) atmospheric windows: the N band between 8 to 13μm and the Q band between 16.5 and 24.5μm, respectively. In addition, it features a long-slit spectrometer with a range of spectral resolutions between 150 and 30000.
Publications based on data obtained with the VISIR instrument should quote the following reference paper: Lagage, P.O. et al. 2004, The Messenger 117, 12.
