| LIRIS (Long-slit Intermediate Resolution Infrared Spectrograph) is a near-IR imager/spectrograph for use at the Cassegrain focus of the 4.2m WHT. It was built and developed at IAC and became a common user instrument at ING. LIRIS uses a 1k x 1k HAWAII detector for the 0.8 to 2.5 μm range. The pixel scale is 0.25''/pixel, yielding a field of view of 4.27' x 4.27'.
This webpage provides information for the observer at the telescope and for the planning of an observing run. Extensive documentation about more technical aspects of LIRIS can be found at the IAC LIRIS webpage. News: · August 27, 2007: R=3000 gratings for J and K installed later this year · August 27, 2007: Spectropolarimetry mode offered starting with period 2008A · January 11, 2007: The LIRIS cookbook (PDF) is available! · January 11, 2007: Transmission curves are updated and available in digital format |
