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 × 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.
