Future VLT Instruments: ERIS
28 June 2013
ERIS, the Enhanced Resolution Imager and Spectrograph, is a 1-5 µm instrument for the Cassegrain focus of UT4 at the VLT. It will benefit from the Adaptive Optics Facility (AOF), including the deformable secondary mirror (DSM). ERIS consists of three main instrumental modules:
an AO module, using the AOF DSM and one AOF laser, providing natural and laser guide star adaptive optics correction;
diffraction limited imaging, sparse aperture masking and pupil plane coronagraphy capabilities from 1-5 µm with a 2k x 2k NIR detector;
a refurbished version of the SPIFFI spectrograph, the 1-2.5 µm integral field unit currently in SINFONI, slightly modified for ERIS.
A full listing of the instrumentation development and upgrade projects is available here.
