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.
If you require information which is not yet provided, or if you have suggestions for improving this web site, please do not hesitate to contact us.
